Abstract

PURPOSE: To reduce the distortion of a magnetic disk device, by setting different diameters for hub members such as a hub, a disk spacer, a disk cap, etc. on both surfaces of each magnetic disk.
CONSTITUTION: The different sizes are set for the upper and lower contact surfaces of a magnetic disk 4 to a hub 3, a disk spacer 5 and a disk cap 6 respectively. As a result, the distortion of the disk 4 is extremely reduced. For example, the hub 3, the spacer 5 and the cap 6 are formed in a truncated cone shape respectively. Accordingly, it is hard for one sheet to strain and deform just in a single direction. Thus the distortion of a magnetic disk can be reduced.
