Earlier we reported that Toshiba
claims that their next generation optical storage solution can be produced with
current production facilities, now we can also read on PCworld.com that Toshiba will pack 36 GG on one disc,
the size of a CD/DVD. The new format is called AOD and it competes against the
BluRay format that is currently being promoted and developed by Sony, Philips
and many other electronic giants.
 The
disc, which will be introduced at the Optical Storage 2003 conference in
Vancouver next week, is the same physical size as a CD or DVD and is
capable of storing up to 36GB of data. It is one of two rewritable disc
types that make up the initial AOD format proposal, the other being a
single-sided disc capable of storing 20GB. The AOD format also includes
15GB and 30GB read-only disc types. That compares to between 4.7GB and
9.2GB on a DVD disc.
Both AOD and Blu-ray are able to store more
data than DVD because of the use of blue lasers. Blue light has a shorter
wavelength than the red light used in CD and DVD systems and so the laser
beam makes a smaller spot on the disc surface. That means each bit of data
takes up less space on the disc and so more data can be stored on a 12
centimeter disc.
