Patent ID: 7421720

Claim:
An optical disk device, comprising: an optical disk drive mechanism disposed in a housing-shape drive case, the optical disk drive mechanism including an optical head on which a semiconductor laser is mounted, a rotary driver for driving an optical disk, and a transfer mechanism for transferring the optical head, the drive case being disposed in a housing-shape main body case, the main body case internally being partitioned into an area enclosed by the drive case and a deck area having an air hole for outside air; an agitating fan for making air in the drive case flow, and a wind path that allows air within the drive case ahead of the agitating fan to be drawn to the rear of the agitating fan, wherein the air drawn to the rear of the agitating fan is discharged toward the optical head or the semiconductor laser by rotation of the agitating fan, and the wind path is formed so that air below the optical head is drawn, and the drawn air is discharged through the agitating fan toward the optical head or the semiconductor laser, where the optical head is disposed below the optical disk.
