Abstract
To drive the magnetic tape (2), a magnetic-tape apparatus (1) has a drive arrangement (18) comprising at least one brake disc (37, 38) which is rotatable in opposite directions of rotation (30, 33, 27, 36) and which can be braked by a block-brake device (39, 40). The block-brake device (39, 40) includes a brake block (41, 42) arranged on a first level (43, 44), which first lever is pivotally connected to a second lever (47, 48) which is pivotable about a pivot (49, 50). A coupling is arranged between the two levers (43, 47, 44, 48) to provide a positive coupling during braking in one direction of rotation (33, 27) of the brake disc (37, 38), and the two levers are interconnected via a spring to provide a non-positive coupling during braking in the other direction of rotation (30, 36) of the brake disc (37, 38). A single spring rod (61, 62) performs the coupling and the spring functions and has both ends (63, 64, 65, 66) connected to the two levers (43, 47, 44, 48).
