Abstract
In an optical recording system, according to a wobble sync signal obtained from a wobble signal associated with a physical track of a recording medium being recorded with input data by a recording module operated in a default constant angular velocity (CAV) recording mode, operation of the recording module can be switched from the CAV recording mode to a constant linear velocity (CLV) recording mode by a mode control switch. The mode control switch is forced to switch operation of the recording module to the CLV recording mode when result of a comparison between a write clock signal generated from the wobble sync signal when the recording module is operated by the mode control switch in the CAV recording mode, and a threshold signal corresponding to a threshold recording speed in the CAV recording mode indicates that the recording mode should be switched to the CLV recording mode but the mode control switch still keep the recording module staying in the CAV recording mode.
