Pioneer have developed a technology which will allow optical
drives to store 500GB of data . Just stop and think about this
for a moment... 1/2 TB of data! You could store a lot of movies
on one single disk - some 700 - or some 100,000 mp3s. Now that
is just too cool for words. The new technique will use
ultraviolet lasers, which emit shorter wavelength rays than blue
lasers. This makes it possible for the disks to have a capacity
which is something like 20 times that of blue laser Blue-ray
disk.
