ABSTRACT:
In a magnetic tape transport, a tape tension arm is loaded by three different springs to exert three different tension forces laterally against the tape segment anchored between the supply reel and capstan (or supply reel and takeup reel), and the arm has three correspondingly different positions for "play," "fast-forward" and "rewind" modes of operation. The play position of the arm is sensed to provide a play tension at substantially the full value thereof throughout a wide range including the play position, and each pair of tensioning force transmitting elements is arranged to move conjointly and in substantially the same direction so as to avoid frictional shearing motion therebetween.
