ABSTRACT:
A lens cleaner in the form of a disk provided on a compact disk (CD) player using a method for cleaning a pick-up lend of the CD player. Some brushing hair bundles have substantially the same shape as the disk and comprise a plurality of brushing hair bundles planted on a surface of the disk so as to disperse in the circumferential direction and the radial direction. Even though these hair bundles are brought into contact with the pick-up lens, the rotational capacity of the disk is not deteriorated so that the lens surface is not damaged and the lens can be effectively cleaned.
