abstract:In optical storage, constant angular velocity (CAV) is a qualifier for the rated speed of an optical disc drive, 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).
This paper is to display existence and itsconditions to a surfaceacoustic wave propogating along surface of a half-body of piezoelectricceramics with a rotation of constant angular velocity.
