Summary:PURPOSE:To control accurately the position of a disk with a simple constitution, by using a holder part which is supported at the front of a cabinet in a free opening/closing way and an approximately V-shaped holding part for control of disk which is provided at the lower end of said holder part with correspondence to the fringe part of the disk. CONSTITUTION:When a disk 45 is loaded when a cover 23 is opened, the disk 45 is supported by arm parts 69 and 70 of a disk position control member 68 by the empty weight of the disk 45. Then the disk 45 is tilted by holding parts 690 and 700 of the member 68, and the surface part of the disk 45 abutes a front holder 22. When the holder 22 is turned toward an arrow A, the disk 45 is turned together with the holder 22 while its tilting angle is controlled by the parts 690 and 700. Thus the hole of the disk 45 is put opposite to a fitting part 270 of a disk holder 27. When the holder 22 is pressed, it is locked by a lock mechanism. At the same time, the disk 45 is press contected to the holder 27 by a disk clamp mechanism 46.
