constant linear velocity

(storage)
(CLV) A disk driving scheme in which the linear velocity of the disk is kept constant. This requires that the angular velocity of the disk be larger when the reading or writing tracks closer to the axis. The advantage of this technique is that the read/write speed is constant. However, as mechanical stability puts an upper limit on the angular velocity (and not the linear velocity) using the same linear velocity throughout, i.e., using less then the maximal angular velocity at outer tracks means that the full potential of the drive is not used.

So manufacturers started tweaking the relationship between their drives' constant linear velocity (CLV) and constant angular velocity (CAV) functions, and have thereby pushed rewriting up to 8X and 12X.
However, there is an interim step in technology that should not be ignored: the combination of constant linear velocity (CLV) and constant angular velocity (CAV) technology.
The drive also features a 256-KB buffer and Partial Constant Angular Velocity (PCAV), which combines Constant Angular Velocity (CAV) and Constant Linear Velocity (CLV).
