CAV (Constant Angular Velocity) - Definition

CAV is an abbreviation for Constant Angular Velocity. It describes the motion of a body rotating at a constant angular velocity, because as it rotates it moves through a constant angle per unit time. It is an optical disk recording format where the data is recorded on the disk in concentric circles while rotating at a constant speed. When playing back music, a compact disc (CD) employs Constant Angular Velocity to maintain a constant data rate. The motor speed decreases from 495 to 212 rpm as the read head moves away from the center to keep the disc moving past the read head at a constant linear velocity.
