The cassette used comprises a disc (1) accommodated in an external sleeve (2) and retained by a disc holder (7) which closes the front of the sleeve by means of a shutter (8) holding the disc by a retainer. The shutter is latched in the sleeve by a latch (48) which can be moved by an external actuator to remove the disc holder and the disc from the sleeve. A lever (11) releases the disc holder of the inserted disc cassette. An extraction mechanism (11,13,14) withdraws the disc-holder/ disc unit from the sleeve in such a way that the disc and its holder remain inside the appts. after withdrawal of the sleeve.
