の可撓性磁気デイスク装置。[Claims for Utility Model Registration] (1) The driving pin is fitted into the hub engaging hole of the flexible magnetic disk on the turntable by the pressing force of the biasing member, and the driving pin is rotated in the hub engaging hole. The rotational center position of the flexible magnetic disk is brought into contact only with the directional edge, and the rotational center position of the flexible magnetic disk is controlled by the action of a couple generated by the rotational force due to high-speed rotation and the rotational load in the opposite direction to the rotational direction acting on the flexible magnetic disk. The flexible magnetic disk device presses a hub center hole against the shaft of the turntable so that the center hole of the hub coincides with the center position of the shaft of the turntable, and the biasing member is fixed to the turntable and presses the drive pin. What is claimed is: 1. A flexible magnetic disk device comprising: an annular biasing portion that is biased; and an engaging portion that is integrally connected to the biasing portion and engages with a turntable. (2) The biasing member is approximately 18 mm with respect to the drive pin.
A flexible magnetic disk device according to claim 1, which is fixed to the bottom of a turntable at the 0 degree position. (3) The flexible magnetic disk device according to claim (1), wherein the drive pin is fixed to the biasing portion of the biasing member.
