ィスククランプ機構。A circular recess that matches the inner diameter of the disk is formed in the center of the spindle on which the disk is placed, and a plurality of arcuate pieces constituting a hollow cylinder are placed in the circular recess so as to be movable in the radial direction and protrude from the spindle surface. At the same time, a spring is brought into elastic contact between the spindle and the arcuate piece, and the hollow hole of the arcuate piece is inserted from above in order to spread the arcuate piece in the radial direction so as to come into contact with the inner wall of the circular recess of the spindle. 1. A disk clamping mechanism for a magnetic storage device, characterized in that a taper unit that can be fitted into a collet is provided at the center of a collet that presses an upper surface of a disk.
