The document describes a proposed new data storage technology called "Rainbow Technology" that claims to be able to store up to 450 GB of data on an ordinary sheet of paper. It would represent data using colored geometric shapes rather than binary and could store around 2.7 GB per square inch when printed at high resolution. However, experts are skeptical because the claimed storage densities would require unprecedented compression or capabilities beyond current printing and scanning technologies. If proven, Rainbow Technology could provide an extremely low-cost and environmentally friendly alternative to DVDs and hard drives.

3. INTRODUCTION
• Rainbow technology, a breakthrough in digital data storage enables us
to store up to a massive 450 GB on just a piece of paper.
• Rainbow Storage is a group of techniques to store digital data in some
colors, color combinations and some symbols known as rainbow
format, and therefore a rainbow picture will be generated.
• With the help of Rainbow system we would be watching full-length
high-definition videos from a piece of paper.

4. HOW IS IT POSSIBLE?
Data stored in rainbow format on an ordinary paper.

6.  It uses geometric shapes such as squares and hexagons to represent data
patterns, instead of the usual binary method that uses ones and zeros to
represent data.
 Files such as text, images, sounds and video clips are encoded in "rainbow
format" as colored circles, triangles, squares and so on, and printed as dense
graphics on paper at a density of 2.7GB per square inch.
 By printing much higher data encoded capacities can be achieved. The
retrieval of data is done by scanning the paper or the plastic sheet
containing the data into a scanner and later reading it over monitor .

7.  Instead of using 0s and 1s, we use color dots where each color dot can
represent minimum 8 bits (1 byte). The rainbow picture will be highly
compressed and can be represented in any color medium.
 "Although environmental light differences and color shading is a
problem, it can overcome up to a certain limit by using efficient
mapping functions".

8. Process of Storing data
• Printing at 1,200 dots per inch (DPI) leads to a theoretical maximum
of 1,440,000 colored dots per square inch.
• If a scanner can reliably distinguish between 256 unique colors, the
maximum possible storage is approximately 140 megabytes for a
sheet of A4 paper.
• If the scanner were able to accurately distinguish between 16,777,216
colors (24 bits, or 3 bytes per dot), the capacity would triple claims
of several hundred gigabytes.

9. At least one of three things must be true for the claim to be valid:
 The paper must be printed and scanned at a much higher resolution
than 1,200 DPI,
 The printer and scanner must be able to accurately produce and
distinguish between an extraordinary number of distinct color values
 The compression scheme must be a revolutionary lossless
compression algorithm.
a lossless compression algorithm that could store 250 GB
within a few hundred megabytes of data. Likewise, data can be
compressed with any algorithm and subsequently printed to
paper as colored dots.

10. IMPLEMENTATION REQUIREMENTS:
Discs can now be developed from plastic paper
too which will be able to hold 450 GB of data.

11.  The piece of paper or even plastic sheet storing the data has just to be
scanned in the scanner and read over the monitor.
 The developer is simultaneously moulding the technology into 'Rainbow
Cards' which will be of SIM card size and store 5 GB of data equivalent to
three films of DVD quality.
 As 'Rainbow Cards' will become Popular, Rainbow Card Readers will
replace CD drives of mobile phone and computer notebooks
 Large scale manufacture of the Rainbow card will bring down its cost to
just 50 paise.

12. • Principle I
“Every color or color combinations can be converted in to some
values and from the values the colors or color combinations can be
regenerated”.
• Principle II
“Every different color or color combinations will produce
different values”.

13. COMPARISON WITH OTHER
STORAGE DEVICES
CD, DVD’s a thing of past.

14.  Currently, of the several options available for data storage, DVDs are the
best mode, but are yet expensive.
 While a CD costs Rs. 15, his paper or plastic-made RVD will cost just
about Rs. 1.50 and will even have 131 times more storage capacity.
 Using this technology an A4 sheet of paper could store 450 GB of data. In
comparison, a DVD can store 4.7GB of data.
 Paper is, of course, bio-degradable, unlike CDs or DVDs. And sheets of
paper also cost a fraction of the cost of a CD or DVD.

15. ADVANTAGES
 The extremely low-cost technology will drastically reduce the cost of
storage and provide for high speed storage too.
 Files in any format like movie files, songs, images, text can be stored
using this technology.
 The biodegradable nature of the storage devices would do away with
the e-waste pollution.
 The four main storage devices made using this technology are RVD,
Disposable storage, Data Banks, Rainbow cards.

16.  Rainbow cards can be used in mobile devices in place of DVDs & VCDs.
 The rainbow cards can solve this problem. Un-authorized copies of the
films can be controlled to a certain limits using these cards.
 Another theme put forward by rainbow technology is the Data Banks. it is
huge server with a high storage capacity.
 As per a research project done in US in 2003 to store the available static
data, the server required will cost $500 crores(23000 crores). But by using
data banks ,a similar server can be made with Rs.35 lacks.

17. DISADVANTAGES
• The paper has the tendency to fade away hence the data loss may
occur.
• With the extremely low cost of using this technology we can always
afford to have multiple copies.

18. CONCLUSION
 Once the Rainbow technology is in, soon we would be watching full-
length high-definition videos from a piece of paper!
 With the popularity of the Rainbow Technology, computer or fashion
magazines in future need not carry CDs in a pack.
 It should cost a lot less to produce than the typical polycarbonate
DVDs, CDs and now Blu- rays. Huge data banks can be constructed
out of Rainbow-based storage medium.
