ABSTRACT:
In a recording and/or reproducing apparatus comprising at least one magnetic head (29, 30), which is rotatable in a given direction of rotation (31), and at least one tape guide (16) for a magnetic tape (3), which guide is arranged near said head, said tape passes round at least a part of the circumferential surface of the tape guide and past the magnetic head, which rotates at a given level oblique tracks being scanned by means of said magnetic head in a given direction of movement (36) of the magnetic tape, which tracks are each time situated within a longitudinal half of the magnetic tape. In this apparatus means are provided whereby the magnetic tape can also be driven in a direction of movement (37) opposite to the given direction of movement, and by means of a magnetic head (39, 40) which rotates in a direction of rotation (38) opposite to the given direction of rotation and at a further level which is spaced from the given level by a distance substantially equal to half the width of the magnetic tape, tracks are scanned which are situated within the second longitudinal half of the magnetic tape (FIG. 1).
