Hvd high voltage differential hvd(1) (high voltage differential) see scsi and differential signaling (2) (holographic versatile disc) a high-capacity optical disc from the hvd forum (wwwhvd-forumorg) that combines single beam holographic storage and dvd technologies to provide cartridge capacities reaching 1tb and beyond formed in 2005 as the hvd. The holographic technology uses not just the surface of the disc, but the whole area moreover, by changing the angle of the laser, it is also capable to store 350 pages into 1 location the reading of the data does not happen bit-by-bit, but parallel at the same time. The holographic versatile disc (hvd) is a completely new technology in the area of optical data storage by the holographic technology, the amount of the stored data is four times bigger hvd could open the door to develop other areas in technology because it can store vast amount of data on a disc that has the same size like a cd or dvd. Holographic versatile disc structure 1 green writing/reading laser (532nm) 2 red positioning/addressing laser (650nm) 3 hologram (data) 4 policarbon layer.
Nintendo is researching and supporting hvd discs however, the wii u will not use them instead, it will use a proprietary bluray format, with a maximum capacity of about 25 gb. Holographic versatile disc (hvd) is an optical disc technology which would hold up to 39tb of information it employs a technique known as collinear holography, whereby two lasers, one red and one green, are collimated into a single beam. A technical committee, tc44 to discuss the standardization of holographic versatile disc (hvd) was approved at 88th ecma international general assembly on december 9th 2004. Holographic memory has been around for more than 40 years, but several characteristics made it difficult to implement in a consumer market first off, most of these systems send the reference beam and the information beam into the recording medium on different axes.
Hvd (holographic versatile disc) is the next generation in optical disk technology hvd is still in a research phase that would phenomenally increase the disk storage capacities over the currently existing hd dvd and blu-ray optical disk systems according to published statistics, when produced in. The holographic versatile disc (hvd) is an optical disc technology developed between april 2004 and mid-2008 that can store up to several terabytes of data on an optical disc 10 cm or 12 cm in diameter. A holographic versatile disc uses two lasers, red and green, to store information at higher densities than traditional optical discs the red laser locates data the green laser reads the actual.
A holographic versatile disk hvd is just slightly larger than a dvd and can store 30 times as much data inphase technologies announced that they would release the first commercially available holographic drive in may 2008 inphase's drive, the tapestry, costs $18,000 (usd.
