Constant angular velocity
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).
