Abstract
A recording and/or reproducing apparatus (1) can hold a magnetic-tape cassette (2), which accommodates a supply reel (3) including a first magnetic circuit element (42) and has a disc-shaped drive member (47) including a second magnetic circuit element (49), the two magnetic circuit elements (42, 49) forming magnetically acting holding means (43) for holding the supply reel (3) in the apparatus (1) and the disc-shaped drive member (47) having magnetic-force-of-attraction limiting means (51) which serve to and are adapted to cooperate with the first magnetic circuit element (42) and which enable the magnetic force of attraction produced between the two magnetic circuit elements (42, 49) to be limited.
