Abstract

PURPOSE:To remove the dust stuck on an objective lens by stopping a pickup for specific time at the position where the objective lens is opposed to the outer peripheral face of a disk and abutting the air stream caused by the rotation of the disk to the objective lens. CONSTITUTION:The disk driving means (spindle motor) 21 generating an air stream by rotating a disk 10 at high speed, the optical member (objective lens) 107 for making the recording of an information onto the disk 10 or the reproducing of the information from the disk 10 optical and the pickup 31 capable of advancing and retreating, etc., are owned, and when the pickup 31 reaches an opposing position, it is made to stop temporarily. The objective lens 107 is then located at the position receiving max. the air stream caused by the rotation of the disk 10 when a supporting base 30 stops at a position Q, and this air stream abuts the objective lens 107. The dust stuck on the lens 107 is thus blown off and removed.
