Fresh from Comdex, here are the specifications on the new
(no prices yet) 6.8 GByte Kodak double sided write once
14" optical disc drive.   It is organized in five constant speed
bands, meaning you have to change the angular velocity of the disc
when you switch from band to band.   There is also a concept
called a 'window', which essentially refers to the ability of
the tracking mechanism to select one track out of some.
