ABSTRACT:
An optical disk apparatus optically records and reproduces data from an optical information recording medium by an optical head. A first chamber is formed to accommodate at least an optical disk cartridge accommodating therein the recording medium and the optical head and is isolated from ambient air. The first chamber is spatially isolated from heat sources, such as a power supply or a circuit board package which needs cooling. Ambient air is supplied to the heat sources while bypassing the first chamber. In this manner, dust contained in ambient air is prevented from adhering to optical parts such as the optical disk and the optical head.
