ABSTRACT:
A recording and/or reproducing apparatus (1) for a magnetic tape includes two winding spindles (13, 14) for driving winding hubs (9, 10) mounted coaxially thereon and a drive mechanism (15) for driving the winding spindles (13, 14). The drive mechanism (15) comprises a first drive wheel (46) which is selectively drivable in one of two directions of rotation and which drives a second drive wheel (48) via a coupling device (49), which second drive wheel can be coupled to one of the two winding spindles (13, 14) depending on its direction of rotation. The coupling device (49) comprises two friction couplings (51, 53) arranged coaxially between the first and second drive wheels and adapted to transmit different torques. A unidirectional coupling (55) bypasses the friction coupling (53) for the transmission of the smaller torque in the case of a direction of rotation (56) so that the device transmits different torques in opposite directions of rotation. By means of this drive mechanism (15) the two winding spindles ( 13, 14) can be driven with different torques, so that the torques of the winding spindles (13, 14) are adapted to the different friction effects on the magnetic tape (11) when this tape is wound on the winding hub (9) and the winding hub (10).
