While the optical storage industry is caught up in the Blu-ray vs. HD-DVD debate, it seems as if the battle lines are being drawn for what might turn out to be the next standards skirmish: holographic storage. Work on the technology began more than 40 years ago, and two companies -- InPhase Technologies of Longmont, Colo., and Japan's Optware Corp. with its Holographic Versatile Disc (HVD) -- will finally ship the first commercial offerings late this year. InPhase's first Tapestry drive, the HDS-300R, will use 300 GB write once disks designed for professional archiving, complete with RFID identifiers. It has a SCSI interface, a 20 MBps transfer rate, an MTBF of 100,000 hours, and a rewritable design will follow. InPhase says the drive will scale to 1.6 terabytes (TB) by 2009 and is planning other products like a 2 GB postage stamp-sized device and 210 GB on a credit card-sized unit. RFID identifiers.

Optware's first HVD product, the HVD Pro Series 1000, will store 200 GB on a disk very similar -- and, in fact, somewhat compatible -- to DVD. By spacing the holographic cones at three micron intervals, the company has experimentally verified up to 3.9 TB at a transfer rate of 1 Gbps. Optware promises today's drives will be able to read tomorrow's disks, all the way up to the 3.9 TB version. Optware has submitted HVD to the European Computer Manufacturers Association for standardization, and it will eventually go to the International Standards Organization. read more
