300GB DVD launches next month

Consumer version coming within two years

Hitachi Maxell plans to demonstrate a 300GB version of a holographic optical disc this week that will be available to select customers in the entertainment industry beginning next month.

InPhase Technologies, which was spun off from Bell Laboratories in 2000, is producing the holographic disc - called the Tapestry HDS-300R. The launch of the product to a limited number of customers next month will be followed by a general product release in the first quarter of 2007 aimed at enterprise-class users.

The new DVD is being demonstrated this week at the International Broadcast Equipment Exhibition in Tokyo.

InPhase would not disclose pricing, but it's been reported that the product is likely to retail for $100 to $125 (about £52 to £66) based on the price of Maxell's current Tapestry disk products.

While the first generation of the 300GB DVD is aimed at commercial use, InPhase expects a consumer-grade product launch over the next two years in what it hopes will be a standardised format.

Lisa Dhar, vice-president of media development at InPhase, said the product will first be marketed to the entertainment industry for high-speed, high-capacity film recording, and to enterprise-class companies for data archiving operations. The 300GB product will have data transfer rates of about 20MBps (megabytes per second).

In 2008, InPhase plans a second-generation 800GB rewritable optical disc with data transfer rates of about 80MBps, with plans to expand its capacity to 1.6TB by 2010.
