Toshiba is developing a triple-layer HD DVD-ROM with a data capacity of 45 gigabytes, 50% more than the 30-gigabyte dual-layer HD DVD-ROM disc already announced. A single disc could record up to twelve hours of high-definition movies.
Toshiba also announced a double-sided, dual-layer hybrid ROM disc comprised of dual-layer HD DVD-ROM side and dual-layer DVD-ROM side. The hybrid disc can store 30GB of high-definition content on the HD DVD-ROM side and 8.5GB of standard-definition content on the DVD-ROM dual layer side.
Memory-Tech Corporation, Japan’s largest independent disc replicator, has confirmed the new 45GB and hybrid discs can be produced on their existing manufacturing lines and equipment, which are tailored to produce HD DVD discs, with only minor additional investment and minimum additional production cost per disc.
Toshiba presented its innovations at this week’s Media-Tech Expo 2005 in Las Vegas. http://www.toshiba.co.jp/about/press/2005_05/pr1002.htm
