PURPOSE:To prevent cleaning members from coming out of a disk even when the disk is rotated at high speed at the time of using the lens cleaner having a large number of cleaning members flocked in a dispersion pattern on the disk by shifting their positions from one another in the circumferential direction and also in the radial direction. CONSTITUTION:In a signal recording area 5 of the disk 1, a hole 6 is provided in a flocked point of each cleaning member 2. The cleaning member 2 consists of a bundle 10 of brush bristles and a chip 7 fixing this bundle. The inner circumferential side surface of the hole 6 and the outer circumferential side surface of the chip 7 are formed into a tapered shape to be engaged with each other, where the chip 7 is fitted into the hole 6. |
