发明名称 Method and apparatus for controlling power during recording of a visible image in an optical storage medium
摘要 A controlling unit 130 of an optical disc recording apparatus judges a failure of a focus servo in accordance with an output signal of a servo circuit 107 . When a failure of the focus servo is detected, a laser light irradiating position at the time of the failure is obtained as a standard position and a laser power controlling unit 140 is controlled to pause a control of the laser power based on data to be recorded. Thereafter, the laser power controlling unit 140 and a position of an optical pickup 103 are controlled to restart the control of the laser power based on the data to be recorded from the standard position as a starting position.
