Toshiba has succeeded in extended the data capacity of HD DVD. The Corporation has used the Las Vegas CES to unveil a triple-layer HD DVD-ROM with a capacity of 51 gigabytes.
The new ROM disc has a three-layer structure, with each layer storing 17GB of data, able to store up to 7 hours of high-definition video. The boost has been made possible by an improvement in disc mastering technology. The new discs are fully backwards compatible with existing HD DVD players. The 51GB 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. Toshiba says that it expects the format to be officially sanctioned by the end of 2007, with software appearing in 2008.
