Triple layer HD DVD gets the thumbs up

Standard single- and dual-layer HD DVDs offer 15GB and 30GB of storage, respectively. Adding a third layer would have taken the overall capacity to 45GB, still less than a 50GB BD, so Toshiba’s boffins worked to get an extra 2GB onto each layer of the three-tier HD DVD. The Forum is also investigating a further format, one that fits a standard, single-layer DVD to the back of a two-layer HD DVD in order to allow standard definition content to be included for ordinary DVD players, effectively future-proofing the disc. The format is expected to be approved before the end of the year.
