ABSTRACT:
An optical disc apparatus capable of obtaining an effect to reduce the laser noise without shortening the laser diode service life or increasing the power consumption. The optical disc apparatus includes a laser diode for emitting a laser beam, a laser driver for driving the laser diode, a detector for monitoring a first power emitted from the laser diode, a detector for monitoring a second power applied to an optical disc, and an attenuator for attenuating the first power. The light attenuation factor of the attenuator is changed by the ratio between the first power and the second power.
