HD Tech Advances

9 Jun, 2005 By: Erik Gruenwedel

Japanese electronics manufacturers TDK Corp. and Toshiba Corp. have announced technological advances in the ongoing race to market competing Blu-ray Disc and HD DVD formats.

TDK Corp., a member of the Blu-ray Disc Association board of directors, said it has produced a prototype Blu-ray Disc with 100GB capacity — twice the size of the format's 50GB disc. The disc, which incorporates four 25GB layers, would be capable of storing up to 9 hours of high-definition video and could record data at 72Mbps — twice the 36Mbps rate of the current Blu-ray product.

Toshiba has reportedly created production infrastructure capable of mass-producing a write-once 15GB HD DVD-R disc, which is expected to be available early next year.
