In a joint project, Memory-Tech and Toshiba today announced that the two firms have developed a one-side, three-layer disc for both DVD and HD DVD formats. The new technology will pave the way to higher capacity hybrid storage on a single disc.
The new disc is an addition to Toshiba's existing DVD TWIN format, which support both DVD and HD DVD storage types. The three-layer discs will allow for either two HD DVD layers and one DVD layer, or two DVD layers and one HD DVD. When configured to the former, close to 35 GB can be stored (30 GB of HD DVD and 4.7 GB of SD DVD). Alternatively, the technology can also accommodate a dual-layer DVD (8.5 GB) and one HD DVD layer (15 GB).
