Abstract

Abstract A record player in which a magazine is provided with compartments for storing a number of rigid and flexible disk-shaped recording media. For playing the disks, they are removed only to an extent necessary for the disk drive to engage bores of the disk. Each compartment has a bottom with a semi-circular recess at a side of the magazine from which the recording media are removed for being played. This recess has a diameter that is substantially longer than the diameter of the respective disk to be played, so that the disk can rotate freely while being played. Each compartment, furthermore, as a storage recess above the semi-circular recess for storing the disk. To play the disk, the latter is lowered from the storage recess into the semi-circular recess, but the lowering of the disk is such that the disk will not contact the bottom of the semi-circular recess, so as to allow free rotation of the disk within the semi-circular recess.
