InPhase Technologies and Maxell Corporation have just turned Holographic storage from a virtual dream, to reality. The first ever public demonstration of holographic data storage systems will take place at the National Association of Broadcasters (NAB) convention next week in Las Vegas. The prototype to be shown is of a 300 GB drive that uses InPhase’s patented two-chemistry Tapestry photopolymer write-once material. The recording material is 1.5mm thick and is pancaked between two 130mm diameter transmissive plastic substrates.
Not only is Holographic storage small, it can record 1.4 GB of data in about the size of your finger nail, it’s fast too, with data reading speeds of around 60 milliseconds to recover 30 seconds of video. InPhase Tapestry holographic drives will have capacities that range to 1.6 terabytes (TB) on a single disk. The prototype drive uses a small SCSI interface and works with the Pegasus Disk Technologies Windows device driver. This presents the device as a drive letter with complete random access, in less than 200 milliseconds, to any file on the holographic disk.
Commercial units are expected to be delivered to OEM customers in 2006.
(Holographic storage is recorded by two laser beams, one beam references the location, the other beam sends the data.)
