Zusammenfassung:	PURPOSE:To perform the reproduction of both sides of a disk with one optical head without turning out the disk by moving and inverting the one optical head so as to correspond to both sides of the disk. CONSTITUTION:A signal on the rear side of the disk D is read out and reproduced with the optical head 11 by moving a head supporting body 10 in the radius direction of the disk D along a lower frame 3 at a state where the optical head 11 is confronted with the rear side of the disk D. When the reproduction of the rear side of the disk D is completed, the head supporting body 10 is elevated and moved from the lower frame 3 to an upper frame 2 with an elevation mechanism 16, and the head 11 is inverted to a down state corresponding to the surface of the disk D with an inversion mechanism 26. In such a way, the signal on the surface of the disk D is read out and reproduced with the head 11 by moving the head supporting body 10 in the radius direction of the disk D along the upper frame 2 from a state where the head supporting body 10 is elevated and the head 11 is inverted.
