Holographic Storage Coming Soon Maxell and InPhase Technologies say that holographic data techniques would store 150 million pages, or 63 times the capacity of a DVD, on a single 5.25-inch disc. Lasers and 3D holographic images would store and retrieve data at ultra-high densities and could ultimately put 1.6TB of data on a single disc with transfer speeds of up to 120Mbps. “Unlike other technologies that record one data bit at a time, holography allows a million bits of data to be written and read in parallel with a single flash of light,” says Liz Murphy, VP of marketing at InPhase Technologies. Expect an early 300GB, 20Mbps model later this year.I recall seeing a documentary about 10 years ago about NASA working on a project to put data on a 1"x1"x1" plastic cube, that would be accessed using two lasers to look into the matrix for a dark or clear spot. They said you could use many discrete frequencies of laser light and begin the storage capacity all over, so many "layers" of data could be stored simultaneously. I think they said there was about 900 frequencies, so therefore, a single 1" cube would hold all of the Library of Congress and have room to spare. Maybe they are getting close...I'm sure the RIAA will not like this development.
