ABSTRACT:
A magnetic tape cassette comprises a housing open on one side and, movable therein, a sheath enclosing a magnetic tape roll. Detachable retaining means in the cassette hold the sheath and the roll in position while the cassette is not on the recorder. The retaining means are detachable by unlatching means when the cassette is fitted to the recorder, so that, following a movement of the sheath, the cassette is opened to allow the roll to emerge at least partially from the cassette and the circumference of the roll to be rotated by means of a recorder-associated capstan provided outside the cassette. Further advantageous embodiments of the invention concern the cassette and the recorder. The cassette of the invention and the recorder associated therewith can be employed in all fields of magnetic tape recording and reproduction. Its application to a magnetic tape system with a self-threading tape end entails advantages.
