Toshiba and co-developer Memory-Tech announced yesterday that the single-sided, three-layer ROM disc offers a storage capacity of 30GB on the HD DVD side, and 4.7GB of standard DVD capacity. The technology would be a major improvement over the double-sided HD-15 (15GB)/DVD-9 (4.7GB) combo discs currently on the market.
Currently, HD DVD backers Universal and Warner are the only studios that have released disc titles using existing double-side HD DVD/DVD combo technology. However, with increased storage capacity and the appeal of a single-sided disc, Toshiba's prototype, if perfected, could usher in more widespread industry and market support for the combo format.
Toshiba and Memory-Tech plan to introduce the prototype to the HD DVD Forum in the coming weeks, after a successful test marketing run in Japan that began last April.
