Claims

[Claims for Utility Model Registration] A circular recess fixed to the rotating shaft of the drive motor and centered on the axis of the rotating shaft, and a disk receiving surface along the periphery of the circular recess; a spindle in which a circular centering taper guide centered on the axis is formed on the bottom; a disk rotatably attached to the hub frame corresponding to the spindle and corresponding to the disk receiving surface; a hub having a pressing surface; a disk guide suspended from the hub in a floating state and tapered from an outer circumference that abuts the inner circumference of the circular recess; and a disk guide formed at a lower end of the disk guide and configured to A collet is provided with a sliding portion concentric with the outer peripheral portion guided by a centering taper guide, and the collet is fitted into a center hole of a flexible magnetic disk to be loaded, and the disk is inserted into the center hole of the flexible magnetic disk. A disk clamping mechanism for a flexible magnetic disk drive device, characterized in that the flexible magnetic disk is centered and clamped between a receiving surface and a disk pressing surface.
