Sanyo Plots 100GB Blu-ray Discs

Sanyo has unveiled plans for a new type of blue laser diode, which it said could support four-layer 100GB Blu-ray discs.

Emitting 450mW, nearly double the 250mW from existing lasers, the new laser could write to Blu-ray discs at 12x speed over four layers of 25GB each.

The new standard would require approval from the Blu-ray Disc Association before it could display the Blu-ray logo, and Sanyo hopes products will be available before 2011.
