Abstract: The system and method is used for CAV (Constant Angular Velocity) control format recording, whereas the existing disk data is recorded under CLV (Constant Linear Velocity) control format recording. When the PUH receives a laser driver signal, it generates a feed signal and a wobble signal. The feed signal is received by the automatic power control; thereafter the automatic power control generates a first control signal used for causing the laser driver to adjust the laser driver signal. After the ATIP decoder receives the wobble signal, the ATIP decoder generates and outputs ATIP decoded data to the CLV value detector. The CLV value detector receives ATIP decoded data and generates a CLV decoded data to the laser power control. The laser power control receives the CLV decoded data and generates a second control signal used for causing the automatic power control to adjust the first control signal.
