Claims

[Claims for Utility Model Registration] An elongated hole is provided near the center hole of the recording/reproducing disk, and the surface of the elongated hole on the outer circumferential side of the disk is inclined with respect to a reference line parallel to the tangent to the outer circumference of the disk. A center pin and an eccentric pin are each fixedly provided on a disk table which is formed into a surface and rotationally driven by a motor, and the disk is mounted on the disk table and the center hole and the elongated hole are connected to the center pin and the eccentric pin. A recording device configured such that the eccentric pins are inserted into the respective pins and the disk table is rotated in one direction by a motor in this state, thereby pressing the eccentric pins against the inclined surface of the elongated hole by a wedge action to rotationally drive the disk. Rotational drive device for playback disks.
