IPC: G11B33/12
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a disk clamp which can secure the even clamp load in the circumferential direction with rotation-stopping pin holes maintained as they are. SOLUTION: The fringe part of the rotation-stopping pin holes is bent, so as to secure even clamp load in the circumferential direction of a disk clamp having the rotation stopping pin holes.
