DVD Forum Approves Three Layer 51GB HD DVDs

At its 40th Steering Committee Meeting, the DVD Forum has approved the triple-layer HD DVD ROM (read only) specification proposed by Toshiba.

The new HD DVD ROM disc has a three-layer structure, with each layer storing 17GB of data, offering a total disc capacity of 51 gigabytes. Currently, HD DVD ROM has a single-layer capacity of 15 GB, with dual-layer discs offering 30 GB.

The new disc, which can store up to 7 hours of high-definition video, 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.

With this latest development, the HD DVD camp is able to offer a product that matches the capacity offered by a dual-layer Blu-ray Disc.
