This is a recording/reproducing disk chucking device having an eccentric hole for transmission, and includes a substantially circular disk receiver that is attached to a rotary drive shaft that engages with the center hole and rotates integrally with the rotary drive shaft; a chucking magnet fixed to the disk receiver, which attracts the suction plate and places it on the disk receiver; and a driving pin, which is pivotally fixed to the front disk receiver and engages with the eccentric hole to drive rotation. In the state in which the suction plate is attracted to the disk receiver, the suction force of the chucking magnet to attract the suction plate is made almost uniform around the outer periphery of the disk receiver. A recording/reproducing disk tracking device characterized by: (2) The recording/reproducing disk chucking device according to item 1, wherein the magnet shape is approximately annular and is disposed around the outer periphery of the drive pin.
