Toshiba announced on Tuesday the development of a higher-capacity HD DVD disc. HD DVD is the format the electronics maker is promoting as the next-generation DVD disc format. Previous versions of the format allowed for the storage of up to 30GB, but the latest version can read into a third layer on an HD DVD disc so it can hold up to 45GB of data. The 45GB version of the disc is a read-only version. Toshiba also announced a double-sided, dual-layer, hybrid read-only disc storing up to 30GB on the HD DVD side of the disc and 8.5GB on the standard DVD dual-layer side of the disc.
The increase in disc storage capacity is partly in response to a competing format, Blu-ray Disc, which supporters such as Sony are also trying to establish as the next-generation DVD disc format. Blu-ray Disc can store up to 50GB of data on a dual-layer disc.
I thought that the HD-DVD was about minumum change and cost. Three layers will just make manufacturing (of both player and media) more expensive. Besides, is it smart to announce upgrades before the current version is out? Weird.
