Claims

[Claims for Utility Model Registration] 1. In a flexible magnetic disk device in which a flexible magnetic disk rotates, a donut-shaped disk-shaped part centered around the magnetic head is placed on the lower and upper sides of the flexible magnetic disk. When the flexible magnetic disk is stopped, the upper part placed on the upper side is separated from the lower part placed on the lower side, and when the flexible magnetic disk is rotating, a constant load is applied to each of the upper part and lower part. The flexible magnetic disk is sandwiched between the parts, and the sliding end surface of the lower part is fixedly arranged below the magnetic head when viewed from the flexible magnetic disk, with the sliding end surface of the lower part being spaced a certain distance from the height of the gap part of the magnetic head. A flexible magnetic disk holding mechanism featuring: 2. The holding mechanism for a flexible magnetic disk according to claim 1, wherein the magnetic head having the lower part fixed thereon and the upper part are fixed by a leaf spring.
