ABSTRACT:
In the magnetic recording and reproducing apparatus disclosed, a loading arrangement displaces magnetic tape between a position where the tape's running path from a tape supply member to a take up member relative to a recording and reproducing arrangement makes it possible to record and reproduce and a position where such recording and reproduction is disabled. A transfer friction arrangement between a tape drive and the supply member or the take up member changes its frictional operation depending upon the tape running path controlled by the loading arrangement. According to a specific embodiment disclosed, the drive is shiftable between a direct direct mode when the tape is disabled from recording or playback and a slip torque transmission mode when the recording-playback is enabled.
