Abstract
Cassette includes a disc (1) accommodated in an external sleeve (2) and retained therein by a disc holder (7) which closes the front of the sleeve (2) by means of a shutter (8), which retains the disc by retaining jaws (9), and which is latched in the sleeve by latching means (48) which can be moved by external means to remove the disc holder and the disc from the sleeve. Apparatus includes release levers (11) which release the disc holder (7) and an extraction mechanism (11, 13, 14) which withdraws the disc-holder/disc unit from the sleeve in such a way that the disc and disc holder remain inside the apparatus after withdrawal of the sleeve. Jaws (9) also retain the disc (2) outside the sleeve and can be moved relative to each other from the retaining position to a free position, in which the disc can be rotated and is clear of the retaining means, by external means only. Apparatus includes release means (11, 15, 20, 24) which ensure that inside the apparatus the jaws (9) are moved from the retaining position to the free position.
