PURPOSE:To provide function for removing wear powder to a jacket and to reduce wear of a metallic thin film medium by folding back a part of a liner to disk side so as to form a part having the removal function of wear powder. CONSTITUTION:An opening 1, a contact part 2, a bag part 3 and a back part 4 are produced by folding a part of the liner to the disk side, and the four parts form the wear powder removing section. When the disk is turned from the opening 1 to the back part 4, the large wear powder adhered to the disk 7 is blocked by the opening 1. When the wear powder is stored and the amount is increased, the powder is pushed into the bag part 3 by a force produced by the rotation of the disk. Fine powder not stopped at the opening 1 slips under the contact part 2 while being adhered to the disk 7 and is clung to fibers of the liner 6. When the disc 7 is rotated from the back part 4 to the opening 1, the wear powder is blocked at the back part 4 and removed similarly. |
