Abstract
To provide for positive guidance of magnetic tape, particularly for video tape recording (VTR) apparatus, in which the tape can move in either direction of rotation, tape is guided tangentially over a capstan (14) and pressed thereagainst by a pressure roller (15) which is so positioned that a line connecting the axes of the capstan (14) and the pressure roller is perpendicular to the tangential engagement of the tape (2) with the capstan (14); the pressure roller (15) is supported in this position by a support or counter roller (18) located adjacent the pressure roller in at least part-surface contact therewith, preferably at the edge zones where magnetic tape does not contact the pressure roller, and in a line parallel to the tangential engagement of the tape, resilient spring force means (114, 114'; 118, 118') being provided to press the pressure roller against the capstan and against the counter or support roller, tangential engagement of the tape permitting operation of the transport arrangement in either direction of movement and resilient engagement of the pressure roller preventing pinching or misalignment.
