ク状記録媒体のセンタコア。[Scope of Claim for Utility Model Registration] A center core portion having a center hole into which a rotating shaft of a disk drive device is inserted for holding a flexible recording disk and centering the disk;
The core portion includes a magnetic core plate, and the inner periphery of the center hole of the core portion includes a positioning surface that is in contact with the circumferential surface of the rotating shaft, and the core plate is provided with a tracking surface of the recording/reproducing device. In the center core of a disk-shaped recording medium that is chucked by magnetic attraction to a plate, a chucking spring is provided which is rotatably supported so that one end thereof is tilted toward the center of the center hole, and the core plate The other end of the chucking spring is pressed by the magnetic force between the chucking plate and the chucking plate, and the reaction force presses one end of the chucking spring against the rotational drive shaft to position the positioning surface of the center core on the rotational drive shaft. A center core of a disk-shaped recording medium characterized by:
