Technology of Taiwan Unveils Prototype Optical Disc .
January 15
, 2002 (LAS VEGAS, Nevada)-Optodisc Technology Corp. of Taiwan exhibited
a prototype next-generation optical storage media using a blue-violet
laser for its light source.
The company
showed the prototype at the 2002 International Consumer Electronics
Show.
The thickness
of the disc's cover is 0.1 millimeter. The cover uses the numerical
aperture of the objective lens to 0.85. Many makers of optical discs
use this combination for R&D purposes.
The exhibited
prototype is a phase change optical storage media, a monolayer on
one side with a 25GB recording capacity.
Currently,
many manufacturers use different recording capacities for the next-generation
optical storage media, including 23.3GB, 25GB and 30GB.
Optodisc
decided on 25GB because it expects that most of such makers will
focus on 25GB, a company spokesman said.
