DVD Recorder World reports that Maxell plans to make the first Holographic Storage discs commerically available sometime in late 2006. The “Next generation” storage medias of HD-DVD and BLU-RAY each pale in comparison to the current 300GB capacity of the Holographic disc.
Using technology borrowed from the pages of Star Trek (Technology referred to as obsolete in ST:TNG) the Holographic disc employs a pair of lasers: an intersecting signal laser and a reference laser. These laser beams store data in a number of 3D holographic images, each capable of saving hundreds of data pages in a single location. This use of a 3D surface essentially creates several discs on the surface of one disc and hence provides the holographic discs with such massive storage capacities.
While the holographic disc is believed to have a theoretical yet achievable maximum capacity of 1600GB or 1.6 Terabytes, it’s first commerical form will boast a 300GB capacity with a data transfer rate of 20MBps.
While Not a spectacular speed, for a 13 cm disc, that’s a lot of stuff. Optimal for those midnight system backups.
