Toshiba Corp. has created a triple-layer HD DVD-ROM (read only) disc having a capacity of 51 GB. The latest Toshiba HD DVD-ROM 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.

The new Toshiba HD DVD-ROM Disc has a three-layer structure, with each layer storing 17 GB of data. This enhances the capacity over existing ROM discs, which hold 15 GB of data in each layer of a single-sided disc.

Continued development in disc mastering technology has achieved further minimization in the recording pit, supporting a further increase in capacity to 17 GB in single layer and a full 51 GB on a single-sided triple-layer disc. Toshiba has confirmed the disc structure and its successful operation.

The new Toshiba HD DVD-ROM Disc shares the same disc structure as standard DVD and previously announced HD DVD formats: two 0.6-mm thick discs bonded back-to-back. This time-tested physical structure offers proven volume manufacturing at little cost increment.

Toshiba said it aims to secure approval of the new disc by the DVD Forum within this year.

The new Toshiba triple-layer HD DVD-ROM (read only) disc is being showcased at the International Consumer Electronics Show (CES) 2007, in Las Vegas, at the company’s booth.
