Qué (quién) es Constant Linear Velocity - definición
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.

QUALIFIER FOR THE RATED SPEED OF AN OPTICAL DISC DRIVE
Constant Angular Velocity; P-CAV; Partial constant angular velocity
In optical storage, constant angular velocity (CAV) is a qualifier for the rated speed of any disc containing information, and may also be applied to the writing speed of recordable discs. A drive or disc operating in CAV mode maintains a constant angular velocity, contrasted with a constant linear velocity (CLV).
