ABSTRACT:
An optical disk device includes: an optical disk drive mechanism disposed in a housing-shape drive case (2), the optical disk drive mechanism including an optical head (7) on which a semiconductor laser (5) is mounted, a rotary driver for driving an optical disk (8), and a transfer mechanism for transferring the optical head (7); and an agitating fan (12) for making air in the drive case (2) flow. In the optical disk device, a wind path is formed so that the air in the drive case (2) flows in a manner in which it is drawn toward an agitating fan (12) side and the drawn air is discharged toward the optical head (7) or the semiconductor laser (5) by rotation of the agitating fan (12). Therefore, a rise in temperature of the semiconductor laser (5) can be suppressed effectively, while the dust proofing is ensured.
