PROBLEM TO BE SOLVED: To improve a cleaning effect of an objective lens in an optical disk device by attracting a magnetic body of a lens holder in the optical disk device with the magnetic body provided on a disk and cleaning while attracting the objective lens to a cleaning member. SOLUTION: The cleaning member 13 is provided on one surface of the disk and opposite to the objective lens 16, and the magnetic body 12 constituted of iron or a magnet, etc., is fitted into the vicinity of the cleaning member 13. Since the magnetic body 12 attracts the magnetic body 15 of the lens holder 14 in the optical disk device, the objective lens 16 becomes the state being attracted to the cleaning member 13. A turntable 17 is rotated in this state, and the disk 11 is rotated, and the objective lens 16 is cleaned by the cleaning member 13. Thus, the objective lens 16 is cleaned by the cleaning member 13 of synthetic resin, etc., molded to a short hair shape without damaging the objective lens 16. |
