ABSTRACT:
An optical disk device that reads and/or writes information to or from an optical disk. The optical disk device includes a recording signal output unit to output a signal to be recorded on an optical disk, an illuminating device to illuminate a recording surface of the optical disk with a light beam, a light generation control unit to control the intensity of the light beam according to the signal to be recorded, a calculating unit to calculate a value according to the level of the signal to be recorded, a light detector to receive the reflected light from the optical disk and to convert the reflected light to an electrical signal, and a gain adjustment unit to adjust the level of the output signal from the optical detector, based on the gain according to the output value from the calculating unit, and a control unit to control the illuminating device according to the output signal from the gain adjustment unit.
