The DVD Forum will use the 0.6-mm bonded disk proposed by NEC Corp. and Toshiba Corp. as the basis of its next-generation DVD standard utilizing a blue laser. The Forum will not consider the rival blue-laser technology backed by the Blu-ray Consortium, which was not formally submitted to the DVD Forum for consideration.
The standards-setting body had formed two groups earlier this year to study the two optical disk systems. The approach advocated by NEC and Toshiba uses the same 0.6-mm disk substrate employed in current DVDs, while the Blu-ray approach uses a disk with a 0.1-mm cover layer.
NEC and Toshiba jointly proposed the Advanced Optical Disk System to the DVD Forum in August, but the Blu-Ray Disk proponents have not taken a similar step. "As there is no practical proposal of 0.1-mm cover layer disk systems, the working group is virtually dormant," a DVD Forum spokesman said.
