PURPOSE:To prevent dirt on an optical disk face with simple construction by providing plural blades on either an optical disk side or a spindle side. CONSTITUTION:In an optical disk device provided with a clamping mechanism on the upper end of a spindle provided for a disk driving part which is used to mount the optical disk 2 on the spindle by means of a hub 22 at the center part of the optical disk, when the optical disk 2 is rotated, a blade provided on either the side of the optical disk 2 or the spindle forms an air flow along a laser light incident surface. As a result, the opportunity for dust contained in the air to adhere to the laser light incident surface can be reduced. Even when the dust adheres, it is blown out of the optical disk surface by lamina air flow which stays all time and thus, the dirt on the optical disk surface can be prevented. |
