PROBLEM TO BE SOLVED: To enable coping with disks having different outer diameters as a super thin slot-in disk drive unit. SOLUTION: A first rotation arm 35 and a second rotation arm 36 are arranged at both sides acrossing a turntable 23a between them, a base end part positioned at the back side more than the turntable 23a is held rotatably, while a tip part positioned at the front plane side more than the turntable 23a can be swung in the approaching or separating direction in a plane being parallel to the main plane of the disk 2 inserted from the disk insertion opening 19, when disks 2A, 2B having different outer diameters are held inside a plurality of abutting members 38, 39, 40, 50 provided at these rotation arms 35, 36, a center hole 2a of each disk 2A, 2B and an engaging projection part 28a of the turntable 23a are made coincident.
