を具備したことを特徴とするデイスク保持装置。 A turntable having a rotating shaft rotatably driven by a driving means, a disk mounting surface perpendicular to the rotational center line of the rotating shaft, and rotating together with the rotating shaft, and a disk mounting surface of the turntable. By fitting the conical outer circumferential surface into the center hole of the disk, the axis of the rotation shaft is aligned with respect to the rotation shaft so that the center line of the center hole of the disk coincides with the rotation center line of the rotation shaft. a cone-shaped centering member fitted so as to be movable along the centering member, and a centering member interposed between the centering member and the turntable or rotating shaft, the centering member and the turntable or rotating shaft being relative to each other. 1. A disk holding device characterized by comprising a sliding means for freely sliding the disk.
