Toshiba has revealed a new triple layer HD DVD-ROM. Here is the company's statement:
"Toshiba Corporation announced development of a triple-layer HD DVD-ROM (read-only) disc with a data capacity of 45 gigabytes, 50% more than the 30-gigabyte dual-layer HD DVD-ROM disc already announced and enough to record twelve hours of high-definition movies on a single disc. The new disc adds a high-end option to the previous HD DVD-ROM disc lineup that includes the 15GB (single-layer, single-sided) and 30GB (dual-layer, single-sided). These two discs are already approved and standardised at the DVD Forum.
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. More than 84 million DVD players and recorders were produced worldwide in 2004 alone. The standard definition content of the new hybrid discs can be replayed on these platforms, while their owners will also be able to enjoy high-definition content from the same source when they purchase HD DVD players in the future. The new disc further prepares the way for a smooth transition from DVD to HD DVD.
Details of these new discs will be presented at the May 11 HD DVD workshop at Media-Tech Expo 2005 in Las Vegas, U.S., the leading annual trade show for the optical disc manufacturing industry.
All these new versions of HD DVD-ROM discs share the same disc structure as previously announced HD DVD formats, and today’s DVD format: two 0.6-mm thick discs bonded back-to-back, a time-tested physical structure with proven volume manufacturing capability at little cost increment.
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.
Mr. Shiroharu Kawasaki, President and CEO, Memory-Tech, said: “These new HD DVD discs will surely be welcomed by content holders, including Hollywood studios and game developers, as further broadening the scope of future applications. We have already started verification for volume production of triple-layered discs, and we are confident of early verification as they are based on the 0.6mm disc structure and established production technologies. We at Memory-Tech are fully committed to flexibly meeting variety of user requirements.”
