constant linear velocity

storage (CLV) A disk driving scheme in which the linearvelocity 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.
