Claims (1)

[Scope of utility model registration request] In a disk device in which a magnetic head is moved in the radial direction of the disk by a cam plate to form a spiral track on the disk, a pulley to which rotation of a motor is transmitted via a belt and a flywheel integrated with the pulley are used. The lower end of a drive shaft is fixed near the lower end, the cam plate is supported on the upper side of the drive shaft, and the turntable on which the disk is placed on the upper end is fixed. A disk device configured such that a single reduction gear that reduces and transmits the speed to the cam plate is supported by the support to form a unit, and this unitized structure is attached to the chassis of the disk device.
