constant linear velocity
- noun a disk technology in which the disk spins at different speeds according to the track that is being accessed.
- In magnetic and optical storage, the rotating of a disk in a drive at a varying rate, depending on the area of the disk which is being accessed. Since the tracks on the disk are longer as the outer edge is approached, the disk must be rotated more slowly when accessing there, to ensure a constant data read rate. This contrasts with constant angular velocity, in which the disk rotates at a steady rate. Its abbreviation is CLV.
