A compensation method for a front monitor diode of optical disk recorder is proposed for operation in high power operation. A lookup table is established offline by measuring voltage reduction of reading voltage for the front monitor diode with respect to a specific writing voltage. The reading voltage measured by the front monitor diode is compensated for by a reading bias voltage with reference to the lookup table and writing voltage. Therefore, the servo controller can produce stable servo signals to ensure recording quality.
