An objective lens of an optical head is cleaned with a cartridge accommodating a cleaning disk with a brush thereon. The cleaning disk is rotated in apparatus to clean the surface of objective lens provided on the optical head. Simultaneously with causing the rotation of the cleaning disk by driving a spindle motor, the lens is moved toward and away from the disk by driving a lens actuator. Additionally, simultaneous reciprocation of a carriage carrying the optical head toward alternate inner and outer disk peripheries may be caused. Further, the operation of reciprocating the objective lens toward the inner and outer disk peripheries and the operation of moving the lens toward and away from the cleaning disk with the lens actuator may be performed in combination.
