を特徴とするデイスク保持装置。[Scope of Claim for Utility Model Registration] A disk holding device comprising a hub having a rotating shaft and a turntable fixed to the rotating shaft, and fixing the disk to the hub using the magnetic force of a magnet, comprising: a sleeve that loosely fits into the hub; , a yoke coupled to the magnet and movable along the rotation axis is connected by a pin, and by lowering the sleeve, the gap between the disk holding member and the magnet is increased to weaken the adsorption force, and the disk is secured during unloading. 1. A disk holding device characterized by being configured such that the adsorption force applied to the disk is reduced.
