Abstract
A cleaner (C) for an magneto-optical disk device includes a cartridge (), a disk (), an adhesive sheet () stuck to the disk (), a clamping disk (), and a shutter (). The clamping disk () is stored rotatable in the cartridge (), and the disk () is fixed to the cartridge () at a position apart from the clamping disk (). By this means, it becomes possible to safely clean an optical head (). Also, dust can be prevented from scattering to the magneto-optical disk device (P).
