gearing up to start mass production of high capacity
Blu-ray discs capable of storing 100GB of data and churning it out at
8x read speeds.
The extra capacity and performance are achieved by adding additional
layers to the discs. The new discs will feature three or four layers
for 75GB and 100GB capacities. All this is made possible by recent
advances in laser technology and improvements in laser optics. Sharp
will use 405nm blue violet lasers for the new media, while conventional
DVD drives use red lasers with 600nm wavelengths.
However, it's still not clear whether the new discs will be available
anytime soon. Sharp still needs BDA approval for the standard before it
markets it. There were quite a few attempts to make 100GB Blu-ray
drives in the past, but none of them ever made it to retail.
