Optical disk drive for precisely adjusting the intensity of laser light irradiated onto an optical disk

An amplitude detection circuit detects the peak value of an output signal of a photo-detector amplified by a head amplifier. The peak value detected by the amplitude detection circuit is read into a drive controller, and compared with a target value suitable for coding in a binary format a detected signal. The gain of a variable gain amplifier is adjusted accordingly. Consequently, an analog signal processing circuit can stably codify the detected signal in a binary format. Under the control of the drive controller, a recording power level calculation circuit determines a test writing power level with which test writing is performed on a test track of a magneto-optical disk. The recording power level calculation circuit then calculates an actual record power for each zone of the magneto-optical disk according to the test writing power level.
