PURPOSE:To attain long service life and to prevent generation of friction resistance at the normal state by providing a cleaner in parallel with the moving direction of an optical head at a part wider than a recording/reproducing area of a medium, contacting the cleaner onto the recording medium as required by a drive means so as to apply cleaning thereby preventing flaw onto the surface of the recording medium. CONSTITUTION:A high density recording medium 1 is engaged with a medium drive spindle 5 and fixed by a hub 6. Then the spindle 5 is driven and the medium is turned in the direction of arrow 6. Then the cleaner 3 is driven by a driver 4, the cleaning member 8 contacts the surface of the medium 1 to apply cleaning. The size of the cleaner cleaning area 12 of the cleaning member 8 is decided to clean a wider part than the recording/reproducing area 13. Thus, the time when the medium and the cleaner are in contact is short and the medium and the cleaner are not contacted in a normal state.
