constant angular velocity definition storage
(CAV) A disk
driving scheme in which the angular velocity
of the disk is kept constant. This means that the linear velocity
of the disk is larger when reading or writing the outer tracks. The disadvantage of this technique is that the read/write speed varies from track to track. However, as mechanical stability puts an upper limit on the angular velocity (and not the linear velocity) this allows the full potential of the drive to be used.
