Abstract: An optical power level-controlling device controls optical power level of a laser beam irradiated on an optical disk. The optical power level takes an ERASE (reference) level, a lower BIAS level and a higher WRITE level. Recording is performed by alternating the optical power level between BIAS and WRITE levels. In a controlling part, test signals are recorded while varying the optical power level and in an OPC for setting an optimum WRITE level by reproducing the test signals. A combined control, i.e., combination of a feedback control and a fixed value control at a predetermined ratio, is performed on BIAS level during a recording operation of the test signals. Fixed value control is performed on the difference between ERASE level and BIAS level during a recording operation.

Again control amplifier (44) amplifies the HF signal by a gain equal to a reciprocal of the peak held signal to produce an amplified signal.
