The new ROM disc released by Toshiba Corporation has a three-layer structure, with each layer storing 17GB of data. The advances capacity over current ROM discs, which hold 15GB of data in each layer of a single-sided disc. Continued improvement in disc mastering technology has achieved further minimization in the recording pit, supporting a further boost in capacity to 17GB in single layer and a full 51GB on a single-sided triple-layer disc.
The new disc can store up to 7 hours of high-definition video and adds an extended capacity, high-end option to the already extensive line-up of HD DVD-ROM discs. Toshiba aims to secure approval of the new disc by the DVD Forum within this year.
Toshiba has been featuring this new disc at the International Consumer Electronics Show (CES) 2007, in Las Vegas.
