Incredible storage capacity

Called Holographic Versatile Disc (HVD), this emerging technology has been in the works (at least conceptually) for about 20 years. It wasn't until the beginning of the 21st century that real advances were made, however. Holographic disk storage allows for much higher density than DVDs by storing data as light patterns throughout the volume of the polymer disc, or three dimensions. HVD can apparently store up to 60 times the data of a regular DVD and it can read and write data 10 times faster as well.

The two major players in this emerging holographic storage field are InPhase Technologies (an American company) and Japanese firm Optware Corp. Optware recently opened a U.S. branch and intends to launch 200GB HVD drives by the end of 2006; by 2008, the company is aiming to hit the 1TB mark. InPhase also plans on shipping its own 200GB drives by the end of next year. The company has partnered with Hitachi Maxell Ltd. to market the new technology.

According to InPhase, its Tapestry holographic system can store more than 26 hours of broadcast-quality high-definition video on a single 300GB disk, recorded at a 160 megabit per second (Mb/s) data rate. HVD also can hold data for over 50 years without any sign of deterioration, which when combined with its massive capacity makes it an ideal solution for television networks to store all their video.
