ABSTRACT:
A multidisk player comprising a housing, a playback mechanism, a magazine capable of containing a plurality of disks arranged in order, the magazine being detachably fitted in a predetermined magazine loader within the housing, a single adapter detachably fitted in the loader, the single adapter being capable of being loaded replaceably with one disk, disk carrier means for carrying the magazine and the disk in the single adapter to a playback position, and a drive unit for driving the magazine and the single adapter outwardly from the loader, the single adapter comprising a first member directly fitted in the loader, a second member for being loaded with the disk, the second member being movable within a fixed range relative to the first member and along the direction where said first member is fitted in the loader, and a drive unit for driving the second member. The first member is driven out of said loader when the second member is moved relative to the first member such that the sum of the quantity of the protrusion of the first member from the loader and that of the movement of the second member relative to the first member is slightly greater than the outer diameter of the disk.
