storage (CAV) A disk driving scheme in which the angularvelocity of the disk is kept constant. This means that the

linear velocity of the disk be larger when the 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 is used.
