Another factor slowing CD access time: the disk rotates at 500 RPM on the
inside tracks and slows to 200 RPM at the outside.  This could be the
real limiting factor in access time as the head assembly could probabaly be
made to move in well under one second.

Laser videodisc players are available with a 1 secone access time (CAV discs),
this would correspond to 1/2 second if things were reduced directly in
proportion to the amount of head movement.
