The document discusses the Holographic Versatile Disc (HVD), a next generation optical disc format that can store up to 3.9 terabytes of data. HVD uses holographic memory techniques to record information by using the interference patterns of laser light. It has a high storage capacity and fast data transfer rate compared to existing formats like DVDs. The HVD format is supported by many technology companies and movie studios as the successor to DVDs for high definition video and audio storage.
A basic introduction to 'Holographic Versatile Disc' (HVD). HVD is considered as a fouth-generation optical disc. It allows for a storage of about 1 TB with a data transfer rate of 1 GB/sec.

Bi-Directional transceivers, called BiDi’s for short, use two different wavelengths to achieve transmission in both directions on just one fiber. The modules are deployed in pairs, one for the upstream (“U”) direction and another for the downstream (“D”). The standard defining these parts is the IEEE 802.3ah Gigabit Ethernet 1000BASE-BXnn (nn= transmission reach in kilometers) specification for point-to-point Ethernet in the First Mile (EFM) applications.

2. WILL DISCUSS ABOUT What is HVD ? Basics of Holographic Memory Technology Comparison HVD Technology HVD Structure The HVD System: Writing Data The HVD System: Reading Data HVD Capacity How HVD compares ? Advantages HVD Alliance HVD Forum Conclusion References
3. What is HVD? Photo courtesy OptwareHolographic versatile disc Is the next generation in optical disk technology Will have a storage capacity of 3.9 terabytes (39,000 GB) Data transfer rate of 1 GB/s.
4. Basics of Holographic Memory Holography - Method of recording patterns of light to produce a 3-D object. Hologram-The recorded patterns of light. Storing - A laser beam splits into- Reference beam - remains unchanged Information beam - passes through an image. Light interference takes place when these beams intersect. Retrieving – Reconstruction beam is send to a CMOS to sensor to recreate the image. The same concept is used here. The information beam encounters a pattern of light and dark areas that represent ones and zeroes.
6. HVD Technology Uses a technology called ‘collinear holography’. Two laser rays, one blue-green and one red, are collimated into a single beam. Blue-green laser - Read data encoded in the form of laser interference fringes. Red laser (Reference beam) - Read servo information.
7. HVD Structure 1.Green writing/reading laser (532 nm) 2. Red positioning/addressing laser (650 nm) 3. Hologram (data) 4. Polycarbon layer 5. Photopolymeric layer (data-containing layer) 6. Distance layers 7. Dichroic layer (reflecting green light) 8. Aluminium reflective layer (reflecting red light) 9. Transparent base P. PIT
8. The HVD System: Writing 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 Photopolymer recording medium
10. HVD Capacity The entire US Library of Congress can be stored on six HVDs, assuming that every book has been scanned in the text format. The Library of Congress is the largest in the world and contains over 130 million items. 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 3.9 TB HVD can hold anywhere between 4,600-11,900 hours of video, which is enough for non-stop playing for a year.
12. Advantages High Storage capacity of 3.9 terabyte(TB). Edit or reorder programs recorded on the disc. Records one program while watching another on the disc. Automatically search for an empty space on the disc to avoid recording over a program. Backward compatible: Supports CDs and DVDs also. The transfer rate of HVD is up to 1 gigabyte (GB) per second which is 40 times faster than DVD . An HVD stores and retrieves an entire page of data, approximately 60,000 bits of information, in one pulse of light, while a DVD stores and retrieves one bit of data in one pulse of light.
14. HVD Forum The HVD FORUM (formerly the HVD Alliance) is a coalition of corporations purposed to provide an industry forum for testing and technical discussion of all aspects of HVD design & manufacturing. Alps Electric Corporation, Ltd. Optware Corporation CMC Magnetics Corporation Dainippon Ink and Chemicals, Inc. (DIC) EMTEC International (subsidiary of the MPO Group) Fuji Photo Film Company, Ltd. Konica Minolta Holdings, Inc. LiteOn Technology Corporation Mitsubishi Kagaku Media Company, Ltd. (MKM)
15. Conclusion HVD will soon replace previous DVDs. Currently supported by more than 170 of the world's leading consumer electronics, personal computer, recording media, video game and music companies. The format also has broad support from the major movie studios as a successor to today's DVD format. Holographic Versatile Disc already has the backing of seven out of eight leading Hollywood studios. It will soon be able to enjoy a growing range of film entertainment with unsurpassed Full HD pictures and cinema-quality multi-channel sound.
