The Indian steel industry has made a rapid progress on strong fundamentals over the recent few
years. The industry is getting all essential ingredients required for dynamic growth. The
government is backing the industry through favorable industrial reforms, while the private
sector is supporting it with investments worth billions of dollars. Even in the tough times of
economic slowdown, the industry succeeded to sustain its positive growth momentum on the
strong fundamentals of domestic demand from construction, automobile and infrastructure
sectors. With an impressive track record, the country has become a reputed name in the world
steel industry.
In this report a brief overview on the Indian steel industry is given. Its current position and
future outlook is also discussed. Also the Indian steel industry with respect to logistics is also
discussed to certain extent. SWOT analysis for the Indian steel industry is done to find out the
strengths, weaknesses, opportunities and treats faced by the industry.
Logistics and supply chain is one of the key drawbacks for the Indian steel industry. In this
report the current scenario of handling and transportation of steel is discussed briefly. Finally
some measures which are to be taken by the industry to be competent in the global market are
analyzed and discussed.

2. Introduction
Iron and steel represents one of the most energy intensive sectors in any economy and
therefore this industry has such a prominent role. Steel industry in India has dominated the other
energy intensive industries such as aluminum, cement, fertilizers, glass and paper etc. With the
improvement in production technologies and transport means, demand for steel production is
increasing. Due to many reasons such as the infrastructure development in developing countries,
improvements in automobile industry, increasing industrial capacity etc, demand for steel is
increasing drastically. Industries which are closely related to steel industry and helping the
growth of Indian steel industry are power generation, infrastructure, urban and rural
infrastructure and real estates.
There have been almost revolutionary changes in the global steel scene with fierce competitive
pressures on performance, productivity, price reduction and customer satisfaction. National
boundaries have melted to encompass an ever increasing world market. Trade in steel products
has been on the upswing with the production facilities of both the developed and the developing
countries complementing each other in the making of steel of different grades and specialty for
the world market.
Also with increasing concerns such as eco friendly production, reduction in carbon emissions,
safe and hygienic transportation etc made global steel manufacturers to concentrate on
production and supply processes.
The steel industry is also highly material intensive. Generally, 1 tons of steel output requires
handling and transportation of around 4 tons of bulk materials. Therefore, logistics play a
critical role in determining the operational efficiency and cost structure of a steel producer.
According to industry estimates, these costs account for over 15% of the total costs of Indian
producers of steel. In addition, the specific investment (rupees per ton of capacity) requirement
for a steel project is high and therefore the capital outlay for a typical steel project is quite large.
Consequently, success or failure in executing projects may impact the financial health of steel
companies quite significantly.

3. Structure of Indian steel industry:
India has emerged as the 3rd
largest exporter of iron ore behind Brazil and Australia. India stands
in top 10 countries in producing steel in the world. But its global trade only accounts for only
2% of the global steel trade. The domestic steel industry reported rapid growth during the period
between 2003-04 and 2007-08, and steel producers responded positively to this by announcing
large Greenfield or Brownfield expansion projects. Almost all domestic steel companies, along
with some international majors, have announced large expansion projects. While some of the
projects are likely to be deferred or shelved, the capital expenditure for the industry would still
be large, given the high capital intensity of steel projects.
The last decade of the twentieth century will go down as one of the most turbulent phases for
Indian steel industry. The period witnessed sweeping changes in the steel arena, transformation
of self-contained national markets into linked global markets and consequent fierce competition;
oversupply of most kinds of steel resulting in no real appreciation of steel prices and
simultaneous rise in input cost; and most importantly, rise in customer expectations. The
profitability of Indian steel companies has improved in 2009-10 on a quarter-on-quarter basis.
Besides a somewhat improving steel price scenario, a significant softening of iron ore and
coking coal prices has also contributed to this improvement. India with its abundant availability
of high grade iron ore, the requisite technical base and cheap skilled labor is thus well placed for
the development of steel industry and to provide a strong manufacturing base for the
metallurgical industries. Companies in more mature industrial countries like India are
increasingly forced to look to assets (and growth) by setting up production operations (steel
factories) in key developing economies that places then close to natural resource supplies (both
in terms of inputs and energy).
Recent years have witnessed unprecedented turmoil in the global steel market. The crisis in the
international steel market might be attributed to the misbalance between capacity, demand and
production and consequent drop in prices.
Availability of iron ore was and is not an issue, as the domestic production of iron ore is
sufficient to meet demand. Secondary steel producers require closely sized lumps (CLO) which
generate fines. In addition, at the time of mining 60% of the ore comes as fines and balance 40%
3

4. as lumps (including big boulders). Thus, in the total production of iron ore 70-72% are fines
either at the time of mining or while crushing into CLO or handling (loading/unloading)
operations at mines, railway stations or at ports.
India is 5th largest producer of steel with total production of 53.08 MT in 2007. The crude steel
production in India registered a moderate year-on-year growth of 2.7% in 2009 and reached
56.6 Million Metric Tons. On the other side, some Asian countries such as Japan and South
Korea saw significant decline in their production levels. In 2008, per capita finished steel
consumption stood at an estimated volume of around 44 Kg, which represents tremendous
growth potential for coming years. This further signifies the resilience and strength of the Indian
steel industry against external risk factors. Indian steel industry mainly consists of three distinct
groups. The first group comprises the integrated steel producers which produces greater than
1MT and includes Steel Authority of India Ltd (SAIL), Tata Steel (capacity 3 Mt) and Rashtriya
Ispat Nigam Ltd (RINL) (3 Mt). SAIL has four integrated steel plants at Bhilai (4 Mt), Bokaro
(4 Mt), Durgapur (2 Mt) and Rourkela (1.8 Mt). The group of secondary majors consists of the
Ispat Group, Jindal Group, Lloyds and Essar. Their capacities range between 1 Mt and 2 Mt
using a mix of technologies, with much lesser degree of backward integration. These two
strategic groups together hold around 70% of the mild steel capacity in the Indian steel industry.
The third groups of tertiary producers are mini-steel plants, using electric arc or induction
furnaces and are very small in size.
There have been almost revolutionary changes in the global steel scene with fierce competitive
pressures on performance, productivity, price reduction and customer satisfaction. National
boundaries have melted to encompass an ever increasing world market. Trade in steel products
has been on the upswing with the production facilities of both the developed and the developing
countries complementing each other in the making of steel of different grades and specialty for
the world market. The Indian steel industry comprises of the producers of finished steel, semi-
finished steel, stainless steel and pig iron. Indian steel industry, having participation from both
public sector and private sector enterprises, is one of the fastest growing markets for steel and is
also increasingly looking towards exports as driving the growth of the industry.
4

5. The Endeavour is not only in tandem with India's National Steel Policy of achieving a
production level of 110 Mt of crude steel by the year 2020. The timely completion of the
projects for new forthcoming steel plants is of great challenge in the present Indian scenario.
Factors which influenced growth of Indian steel industry:
Factors which were favorable for the growth of Indian steel industry are:
• Global steel consumption: The global steel consumption due to many reasons is
increasing consistently year by year. The main cause is the development of infrastructure
in the developing countries, also with the other growth of other complementary
industries such as automobiles; construction, urban infrastructure etc helped the steel
industry to grow at a rapid pace.
• Implementing latest technologies for improving the quality and productivity also helped
the industry. This led the manufacturers to focus on improving the customer delivery
times and also decrease the costs of production and transportation.
• Making strategic alliances: The manufacturers started making strategic alliances with the
other OEM (original equipment manufacturers) in long term which helped them in
mitigating demand risks and uncertainties, high product take off and better capacity
utilization.
5

6. • Government initiatives: The government policies and initiatives helped the domestic
steel manufacturers to a great extent. This is also key for the growth of the Indian steel
industry. Also, increased infrastructure spending by the Government of India and
development of roads could generate significant savings in freight and transportation
cost, making Indian steel companies and other industries globally competitive.
• Impact of liberalization: The economic reforms initiated by the government in 1991 have
added new dimensions to the industrial growth in general, and steel industry in
particular. Automatic approval granted for foreign equity investment in steel has been
increased up to 74% [Government of India 1999]. Restrictions on external trade, both in
import and export, have been removed. Import tariff reduced from 105% in 1992/93, to
30% in 1996-97.
• Other policy measures like convertibility of rupee on trade account, permission to
mobilize resources from overseas financial markets, and rationalization of existing tax
structure.
Cost competitiveness of Indian steel industry:
The cost of major raw materials like iron ore, coking coal, and other raw materials is less in
India among the countries mentioned. The labor cost is low, but it is neutralized by its low level
of productivity.
The financial cost and the cost of power, oil and some other materials are high. Energy accounts
for about 35 - 40% of the cost of steel production in 13 India, whereas it is about 28% in the
developed countries. All these make the pre-tax cost of steelmaking in India higher than that of
South Korea, Australia, Mexico, and CIS countries.
India has a definite advantage of having low wage rates compared to all the other countries. The
wage rates and other related costs accounts to 15% of the total costs for production of steel, it is
almost half compared with other countries which is 30% of the total costs.

7. Current projects under progress:
• Bhushan Steel plans to invest US$ 5.72 billion for building 12 million ton-capacity in
the states of West Bengal, Jharkhand and Orissa.
• Non-ferrous metals giant, Vedanta Resources, plans to invest around US$ 4.79 billion in
a 5 million ton steel plant in Keonjhar district of Orissa and envisages its commissioning
by 2012–13.
• Tata Steel is also planning to build a 5 million ton plant in Chhattisgarh with an
investment of around US$ 3.59 billion. The steel major is setting up Greenfield projects
in Jharkhand, Orissa and Chhattisgarh. While in Jharkhand it is likely to invest about
US$ 8.38 billion for a 12 million ton integrated steel plant, in Orissa it plans to pour in
almost US$ 4.39 billion for a six million ton capacity plant.
• Mesco Steel plans to invest US$ 2.20 billion for expansion of two of its steel plants in
Orissa.
• Reliance Infrastructure, (part of the Reliance Anil Dhirubhai Ambani Group) plans to
build a 12-million ton steel plant in Jharkhand, which is likely to be completed by 2012.
• Indian Railways plans to invest around US$ 437.25 million per annum to raise its
consumption of stainless steel for adding new alloy-made wagons and coaches to its
portfolio.
• Welspun Gujarat Stahl Rohren, (one of the largest steel pipe makers in India), plans to
increase the capacity of its pipe plant by 75 per cent to 1.75 million tons with an
investment of US$ 222.52 million.
• The JSW group plans an outlay of US$ 40 billion for steel and power projects. These
projects will be completed by 2020.
7

8. • Visa Steel has lined up a US$ 1.51 billion – US$ 2.02 billion integrated steel project in
Chhattisgarh.
• Also, the Confederation of Indian Industry (CII) plans to start six new small and medium
enterprises clusters for steel companies in Visakhapatnam. It will also set up a steel task
force to propel growth in the steel clusters.
SWOT Analysis
Strengths:
• Abundant supply of iron ore
• Low cost and reasonable efficient labor force
• Strong man power capability and improving productivity
• History in steel making and acquired skill
• Strong steel production base and achieved productivity levels
• High degree of entrepreneurship
• Availability of investments and capital back up
• Support from government which helped in growth of the steel industry
Weaknesses:
• Limited availability of coking coal
• High transportation and handling costs.
• Mining costs are also high.
• Implementing latest technology has become a concern for the Indian steel industry.
8

9. • Steel industry in India did not attain self-sufficiency in constructing and efficiently
maintain steel plants. It still relies on the countries like Russia, Ukraine, and Kazakhstan
etc. for installing new steel plant in India.
Opportunities:
• Increase in steel consumption hugely will result in tremendous growth in steel industry
in coming years
• India has all the resources and capabilities to become a global supplier of quality steel
• Low steel prices smooth the way for imports from Russia, Ukraine and Kazakhstan. The
geographical proximity of Japan, South Korea and China makes them important
suppliers as well.
• With the decreased potential for steel in developed countries, India have opportunities
for becoming the world leader in production and supply of steel and iron ore
• Concurrently industries like automobiles and urban infrastructure are also growing
simultaneously.
Threats:
• Infrastructure is becoming a major threat for the steel industry. Insufficient infrastructure
in terms of transportation and logistics is becoming concern for Indian steel industry.
• Huge competition in the global markets. In the Indian markets also, with the entry of the
foreign players the domestic steel producers are facing high market competition.
• Increasing concern for the global climate change is becoming a threat to the industry.
• Future energy use and carbon emissions depend on the level of production and the
technologies employed.
• Issues with dumping of low priced steel products from the Chinese and companies of
other countries is also becoming a barrier for the growth of Indian steel industry.
9

10. • Infrastructure with respect to steel plants and logistics of steel industry is also one of the
key challenges for the Indian steel industry.
Logistics in Indian steel industry
There is a growing concern for the macro and micro level logistics of Indian steel industry.
The customer delivery times, inventory management, cargo handling at ports, procurement of
iron ore and other raw materials are some of the areas in which steel manufacturers are focusing
at micro level. Some of the concerns of logistics for the steel industry at macro level are:
• High transportation costs: This is one of the major concerns which is affecting the
growth of the industry. Due to the problems in infrastructure and also with low levels of
productivity in terms of handling and transporting cargo, the costs of transportation were
soaring day by day.
• Lack of connectivity to the ports with sufficient rail and road networks is also one of the
causes for high transportation costs.
10

11. • Proximity and access to raw materials. Infrastructure development requires the transport
of raw materials for steel production for achieving the goal of 75 million ton of
additional capacity by 2019-20 will require the movement of an additional 300 million
ton of raw material
Future outlook for the Indian steel industry
The sponge iron has of late come up as a major input material for steel making through
electric furnace route – both Electric Arc Furnace and Induction Furnace. Due to long gestation
period, huge investments, dependence for coke on foreign suppliers, the steel industry is slowly
diverting itself from blast furnace route to electric furnace route and the requirement of Sponge
Iron is increasing 67 very fast. Another major reason is the global shortage of scrap. The steel
making furnaces in the eastern region use average 70% Sponge Iron in the feed material for
steelmaking.
The future for the Sponge Iron is therefore quite bright. The steel is today considered as the
backbone of India economy. The growth of economy has a direct relation with the demand of
steel. With the present steel intensity index, considering the GDP projection by the Government
of India, growth of steel demand will be around 11% annually.
As per the National Steel Policy issued by the Ministry of Steel – India will produce 110 million
tons of steel by 2020. The requirement of Sponge Iron as metallic will be 30 million tons. The
Ministry of Steel has decided to come out with a White Paper on the logistics requirement of the
steel industry at a production capacity of 250-300 million tons. The exercise has been prompted
by the logistics constraints in the movement of raw materials and end-products faced by the
country today when steel production is at 65 million tons.
It is expected that India would become the second biggest producer of steel within the year
2016 and the production per year would be 137 million tons.
Today India produce 13.9 million tons of sponge iron, out of which 4.2 million ton is gas based
and remaining 9.7 million ton is coal based. India has a proven reserve of 410 million ton of
11

12. high grade iron ore, another 440 million ton of high grade iron ore which will be established.
India has total 9992million ton of iron ore reserves (as per IBM report of1995).
India has sufficient non-coking coal through of high ash low fixed carbon grade. Coal is used as
a reducing for sponge iron making in the furnace. The availability of scrap of required quantum
is unlikely and therefore scraps needs to be replaced more and more by DRI.
Expanding India’s steel sector depends on lower port costs for handling key inputs such as
coking coal which is predominantly imported, as well as servicing potential steel exports as
envisaged under the National Steel Policy
Some of the measures that the industry has to take in the long term at macro level are:
• High freight rates are the major reason for drastic fall in iron ore loading by railways in
recent months. Plans must be made to reduce the freight rates to improve the growth rate
of the industry.
• Rail transportation can become competitive by increasing line capacity, carrying
capacity of trains, port connectivity etc.
• Road transportation is the most common mode for transport of all goods accounting for
65% of all commodities carried. Measures must be taken so as to improve the
infrastructure of the high ways and fund for the maintenance of the highways.
• Port infrastructure in India is outdated and inadequate resulting in bottlenecks and high
costs. Investments must be invited from domestic and foreign sources to upgrade the
infrastructure at ports, also latest technologies must be implemented to reduce costs and
loading and unloading times.
• Attract FDI’s for investing in coastal transportation and pipeline which are the cheapest
and most reliable modes of transporting iron ore. This will make steel manufacturers
competent enough in the global steel trade.

13. Literature Review
The steel industry is the one which plays an important role in infrastructural development of any
country. It is said to be helpful in 'building nations' especially developing countries like India.
The Indian steel industry anticipates a sufficiently good growth rate in the present five year plan.
The last two decades in India have witnessed a boom in the 'development sector' worldwide.
Especially in developing countries that are rich in natural resources. This has pressurized the
governments to develop large scale projects. There are various risks associated with the phases
13

14. of construction and establishment of a project which are unique and vary from one project to
other.
Concepts of Data Management in steel Industry
Key Concept
How It Relates to Responsible Conduct of
Research
Data Ownership This pertains to who has the legal rights to the data and who
retains the data after the project is completed, including the
PI's right to transfer data between institutions.
Data Collection This pertains to collecting project data in a consistent,
systematic manner (i.e., reliability) and establishing an
ongoing system for evaluating and recording changes to the
project protocol (i.e., validity).
Data Storage This concerns the amount of data that should be stored
--enough so that project results can be reconstructed.
Data Analysis This pertains to how raw data are chosen, evaluated, and
interpreted into meaningful and significant conclusions that
other researchers and the public can understand and use.
Data Protection This relates to protecting written and electronic data from
physical damage and protecting data integrity, including
damage from tampering or theft.
Data Ownership
Understanding data ownership, who can possess data, and who can publish books or articles
about it are often complicated issues, related to questions of project funding, affiliations, and the
sources and forms of the research itself. For federally funded research, ownership of data
14

15. involves at least 3 different entities: the sponsoring institution, the funding agency, and the PI.
In many cases, the institution/organization owns the project data, but the PI and the funding
agency have "rights" to access and use the data.
Data collection
Data collection refers not only to what information is recorded and how it is Data collection
provides the recorded, but also to how a particular research project is designed. Although
information necessary to data collection methodology varies by project, the aim of successful
data develop and justify collection should always be to uphold the integrity of the project, the
research. Institution, and the researchers involved. Once data have been collected and recorded,
the next concern is data storage. Data storage is crucial to a research project for the following
reasons
• Properly storing data is a way to safeguard your research investment.
• Data may need to be accessed in the future to explain or augment subsequent research.
• Other researchers might wish to evaluate or use the results of your research.
• Stored data can establish precedence in the event that similar research is published.
• Storing data can protect research subjects and researchers in the event of legal allegations.

Data analysis
Data analysis is the way raw data is chosen, evaluated, and expressed as the form of data
analysis meaningful content. For many researchers, it would be time consuming and must be
appropriate for the undesirable to use all of the data collected over the course of a study. If it is
project's particular needs.to be translated into meaningful information, data must be managed
and analyzed in an appropriate fashion.
An HVD (holographic Versatile Disc), a holographic storage media, is an
advanced optical disc that’s presently in the development stage. Polaroid scientist
J. van Heerden was the first to come up with the idea for holographic three-
dimensional storage media in 1960. An HVD would be a successor to today’s Blu-
ray and HD-DVD technologies. It can transfer data at the rate of 1 Gigabit per
second. The technology permits over 10 kilobits of data to be written and read in
parallel with a single flash. The disc will store upto 3.9 terabyte (TB) of data on a
single optical disk.
16

17. Holographic data storage, a potential next generation storage technology, offers
both high storage density and fast readout rate. In this article, I discuss the
physical origin of these attractive technology features and the components and
engineering required to realize them. I conclude by describing the current state of
holographic storage research and development efforts in the context of ongoing
improvement to established storage technologies.
1.1 BRIEF HISTORY
Although holography was conceived in the late 1940s, it was not considered a
potential storage technology until the development of the laser in the 1960s. The
resulting rapid development of holography for displaying 3-D images led
researchers to realize that holograms could also store data at a volumetric density
of as much as 1/ where is the wave-length of the light beam used.
Since each data page is retrieved by an array of photo detectors, rather than bi-by-
bit, the holographic scheme promises fast readout rates as well as high density. If a
thousand holograms, each containing a million pixels, could be retrieved every
second, for instance, then the output data rate would reach 1 Gigabit per second.
4.
17

18. In the early 1990s, interest in volume-holographic data storage was rekindled by
the availability of devices that could display and detect 2-D pages, including
charge coupled devices (CCD), complementary metal-oxide semiconductor
(CMOS) detector chips and small liquid-crystal panels. The wide availability of
these devices was made possible by the commercial success of digital camera and
video projectors. With these components in hand, holographic-storages
researchers have begun to demonstrate the potential of their technology in the
laboratory. By using the volume of the media, researchers have experimentally
demonstrated that data can be stored at equivalent area densities of nearly 400
bits/sq. micron. (For comparison, a single layer of a DVD disk stores data at ~ 4.7
bits/sq. micron) A readout rate of 10 gigabit per second has also been achieved in
the laboratory.
1.2 FEATURES
• Data transfer rate: 1 gbps.
• The technology permits over 10 kilobits of data to be written and read in
parallel with a single flash.
18

19. • Most optical storage devices, such as a standard CD saves one bit per pulse.
HVDs manage to store 60,000 bits per pulse in the same place.
• 1 HVD – 5800 CDs – 830 DVD – 160 BLU-RAY Discs.

2. UNDERLYING ECHNOLOGY
2.1 HOLOGRAPHY
Holographic data storage refers specifically to the use of holography to store and
retrieve digital data. To do this, digital data must be imposed onto an optical wave
19

20. front, stored holographically with high volumetric density, and then extracted
from the retrieved optical wav front with excellent data fidelity.
A hologram preserves both the phase and amplitude of an optical wave front of
interest called the object beam – by recording the optical interference pattern
between it and a second coherent optical beam – the reference beam. Fig 2.1
shows this process.
20

21. FIG 2.1 INERFERENCE
6.
The reference beam is designed to be simple to reproduce at a later stage (A
common reference beam is a plane wave a light beam that propagates without
converging or diverging). These interference fringes are recorded if the two beams
21

22. have been overlapped within a suitable photosensitive media, such as a
photopolymer or inorganic crystal or photographic film. The bright and dark
variations of the interference pattern create chemical and/or physical changes in
the media, preserving a replica of the interference pattern as a change in
absorption, refractive index or thickness.
FIG 2.2 HOLOGRAM
22

23. 7.
When the recording is illuminated by a readout beam similar to the original
reference beam, some of the light is diffracted to “reconstruct” a copy of the
object beam as shown in Fig2.2 if the object beam originally came from a 3-D
object, then the reconstructed hologram makes the 3-D object reappear.
2.2 COLLINEAR HOLOGRAPHY
HVD uses a technology called ‘collinear holography’, in which two laser rays, one
blue-green and one red, are collimated into a single beam. The role of the blue-
green laser is to read the data encoded in the form of laser interference fringes
from the holographic layer on the top, while the red laser serves the purpose of a
reference beam and also to read the servo info from the aluminum layer – like in
normal CDs – near the bottom of the disk. The servo info is meant to monitor the
coordinates of the read head above the disk (this is similar to the track, head and
sector information on a normal hard disk drive).
Fig 2.3 shows the two laser collinear holography technique and fig 2.4 shows
the interference fringes pattern stored on the disc.

To read data from an HVD reader. The following components are used to make a
reader.
A blue-green laser, beam splitters to split the laser beams, mirrors to direct the
laser beams, LCD panels (spatial light modulator), lenses to focus the beams,
lithium-niobate crystals or photopoymers, and charge-coupled device (CCD)
cameras.

4. STORAGE DATA
4.1 RECORDING DATA
 A simplified HVD system consists of the following main components:
 Blue or green laser (532-nm wavelength in the test system)
 Beam splitter/merger
 Mirrors
 Spatial light modulator (SLM)
 CMOS sensor
 Polymer recording medium
The process of writing information onto an HVD begins with encoding the
information into binary data to be stored in the SLM. These data are turned into
ones and zeroes represented as opaque or translucent areas on a "page" -- this page
is the image that the information beam is going to pass through.
When the blue-green argon laser is fired, a beam splitter creates two beams. One
beam, called the object or signal beam, will go straight, bounce off one mirror and
travel through a spatial-light modulator (SLM). An SLM is a liquid crystal display
(LCD) that shows pages of raw binary data as clear and dark boxes.
30

31. The information from the page of binary code is carried by the signal beam around
to the light-sensitive lithium-niobate crystal. Some systems use a photopolymer in
place of the crystal.
A second beam, called the reference beam, shoots out the side of the beam splitter
and takes a separate path to the crystal.
When the two beams meet, the interference pattern that is created stores the data
carried by the signal beam in a specific area in the crystal -- the data is stored as a
hologram.

14.
4.2 READING DATA
To read the data from an HVD, you need to retrieve the light pattern stored in
the hologram.
In the HVD read system, the laser projects a light beam onto the hologram -- a
light beam -- a light beam that is identical to the reference beam.
34

35. An advantage of a holographic memory system is that an entire page of data
can be retrieved quickly and at one time. In order to retrieve and reconstruct
the holographic page of data stored in the crystal, the reference beam is shined
into the crystal at exactly the same angle at which it entered to store that page
of data. Each page of data is stored in a different area of the crystal, based on
the angle at which the reference beam strikes it.
The key component of any holographic data storage system is the angle at
which the reference beam is fired at the crystal to retrieve a page of data. It
must match the original reference beam angle exactly. A difference of just a
thousandth of a millimeter will result in failure to retrieve that page of data.
During reconstruction, the beam will be diffracted by the crystal to allow the
recreation of the original page that was stored. This reconstructed page is then
projected onto the CMOS, which interprets and forwards the digital
information to a computer.

5.1 SPATIAL LIGHT MODULATOR
To use volume holography as a storage technology, digital data must be imprinted
onto the object beam for recording and then retrieved from the reconstructed
39

40. object beam during readout. The device for putting data into the system is called a
spatial light modulator (SLM) – a planner array consisting of thousand of pixels.
Each pixel is independent microscopic shutters that can either block or pass light
using liquid-crystal or micro-mirror technology. Liquid crystal panels and micro-
mirror arrays with 1280 X 1024 pixels are commercially available due to the
success of computer-driven projection displays. The pixels in both types of
devices can be refreshed over 1000 times per second, allowing the holographic
storage system to reach an input data rate of 1 gigabit per second – assuming that
laser power and material sensitivities would permit. The data are read using an
array of detector pixels, such as a CCD camera or CMOS sensor array.

To access holographically-stored data, the correct reference beam must first be
directed to the appropriate spot within the storage media. With mechanical access
(i.e., a spinning disk), getting to the right spot is slow (long latency), but reading
data out can be quick. Non – mechanical access leads to possibility for lower
latency. A frequently mentioned goal is an integration time of about 1 millisecond,
which imphes that 1000 pages of data can be retrieved per second. If there are 1
Gigabit per second. This goal requires high laser power (at least 1 W), a storage
material capable of high diffraction efficiencies, and a detector with a million
pixels that can be read out at high frame rates. Frame rates of 1 kHz have been
demonstrated in such “mega pixel” CCDs, but these are not yet commercially
available. Low-noise mega pixel CMOS detector arrays that can support 500
frames per second have also been demonstrated. Even with these requirements
faster readout and lower latency could be reached by steering the reference beam
angle non-mechanically, by using a pulsed laser, and by electronically reading
only the desired portion of the detector array. Both the capacity and the readout
rate are maximized when each detector pixel is matched to a single pixel on the
SLM, but for large pixel arrays this requires careful option design and alignment.

45. It has been estimated that the books in the U.S. Library of Congress, the largest
library in the world, could be stored on Six HVDs.
The pictures of every landmass on Earth - like the ones shown in Google Earth
- can be stored on two HVDs.
With MPEG4 ASP encoding, a HVD can hold anywhere between 4,600-11,900
hours of video, which is enough for non-stop playing for a year.

47. 6.5 STANDARDS
On December 9, 2004 at its 88th
General Assembly the standards body Ecma
International created Technical committee 44, dedicated to standardizing HVD
formats based on Optware’s technology. On June 11, 2007, TC44 published the
first two HVD standards ECMA-377, defining a 200 GB HVD “recordable
cartridge” and ECMA-378,defining a 100 GB HVD-ROM disc. Its next stated
goals are 30 GB HVD cards and submission of these standards to the International
Organization for Standardization for ISO approval.

48. CONCLUSION
A multimodal system, which uses the most efficient modes of transport from
origin to destination, is a prerequisite for the smooth functioning of any port. With
the growth of cargo in the ports by over seven per cent and increase in container
traffic by 17 per cent, the Government had laid emphasis on capacity expansion
and improvement in infrastructure of the ports for handling these growing
volumes of cargo. Unless matched with connectivity infrastructure, the increased
cargo would result in congestion and undermine the competitiveness of Indian
industry and also affect the economy at large.
Though India is technologically forward and advanced in the production of steel
and exporting iron ore, problems with infrastructure and logistics are making it to
lag behind in the international trade of steel and iron ore. Also India should
concentrate on increasing the consumption of steel at the domestic level. The per
capita consumption of steel is the indicator of growth for the developing countries.
The Information Age has led to an explosion of information available to users.
While current storage needs are being me, storage technology must continue to
improve in order to keep pace with the rapidly increasing demand. However,
conventional data storage technologies, where individual bits are stored as distinct
magnetic or optical changes on the surface of a recording medium are approaching
physical limits. Storing information throughout the volume of a medium—not just
on its surface—offers an intriguing high-capacity alternative. Holographic data
storage is a volumetric approach which, although conserved decades ago, has
48

49. made recent progress towards practicality with the appearance of lower-cost
enabling technologies, significant results from longstanding research efforts and
progress in holographic recording material.
HVD gives a practical way to exploit he holography technologies to store data up
to 3.9 terabytes on a single disc. It can transfer data at the rate of 1 Gigabit per
second. The technology permits over 10 kilobits of data to be written and read in
parallel with a single flash. So an HVD would be a successor to today’s Blu-ray
and HD-HVD technologies.
