HD-DVD backers to add three-layer disk

Toshiba Corp. and Memory-Tech Corp. have developed a three-layered hybrid DVD/HD-DVD ROM disk that would enable the reading of two data formats on a single-sided disk.
The partners said they will propose the format to the DVD Forum and hope to make commercially available early next year.
In December 2004, the companies together proposed the DVD Twin Format, a single-side, two-layer disk to store both DVD and HD-DVD content. The format hit the market in April.
The twin format disk has the same structure as the two-layered DVD ROM disk. Two platters with a signal layer are bonded together and the signal is read from one side. The format promises to provide full compatibility between DVD and HD-DVD, and could help ease the transition from DVD to HD-DVD, Toshiba claimed.
"The third-layer Twin disk will provide another option to content providers to create attractive content for consumers," said Masato Otsuka, R&D director for Memory-Tech.
The newly developed hybrid disk has three layers. The DVD layer is closest to the pickup. The farthest layer is for HD-DVD content. The intermediate layer can be used for either DVD or HD-DVD content. Conventional DVD players can read the DVD layer. Link
