Holographic Optical Storage Media|
Each location can hold hundreds of pages of data, and an entire 5¼ inch-diameter optical disc can store millions of pages. Each piece of optical media, which costs up to five times less than videotape, is capable of custom encryption - an essential element in the fight against piracy. The first generation of Maxell Holographic Media is scheduled for release in late 2006.
Maxell Holographic Storage
"Holographic media makes it possible for HD and millions of pages of information to be held on one small, relatively inexpensive disc," said Tony Petruzziello, director of sales for Maxell Professional Media Products Division. "Imagine having a person's entire medical history, complete with MRI data, on a single disc. And imagine having a year's worth of oil exploration geographical data in one small transportable place, or having the ability to store hours and hours of High-Definition video footage on 5¼ inches of disc space. This will all be possible with Holographic media; it's a glimpse into the future."
Holographic Data Storage - Characteristics
Holographic data storage has several characteristics that are unlike those of any other existing storage technologies. Most exciting, of course, is the potential for data densities and data transfer rates exceeding those of magnetic data storage. In addition, as in all other optical data storage methods, the density increases rapidly with decreasing laser wavelength. In contrast to surface storage techniques such as CD-ROM, where the density is inversely proportional to the square of the wavelength, holography is a volumetric technique, making its density proportional to one over the third power of the wavelength. In principle, laser beams can be moved with no mechanical components, allowing access times of the order of 10 µs, faster than any conventional disk drive will ever be able to randomly access data. As in other optical recording schemes, and in contrast to magnetic recording, the distances between the “head” and the media are very large, and media can be easily removable. In addition, holographic data storage has shown the capability of rapid parallel search through the stored data via associative retrieval.
