Abstract
A disk cleaner includes a polishing member which is adapted to be rotated while being engaged with a surface of the disk, thereby to polish the surface of the disk. The polishing member is disposed such that the rotational axis of the polishing member is kept perpendicular to the surface of the disk, thereby to cause the disk to rotate in one direction due to a frictional force between the polishing member and the surface of the disk. The rotational axis of the polishing member is spaced apart from a rotational axis of the disk in the radial direction of the disk, whereby only part of the polishing member engages the surface of the disk.
