ABSTRACT:
In an arrangement (1) for the segment-by-segment recording of information signals by at least one rotationally drivable magnetic head (4, 5) in inclined recording tracks (2) on a magnetic tape (3) which can be driven intermittently by a tape drive device (53) while the recording mode is active, the stationary magnetic tape (3) is scanned along an inclined reproducing track (75) which partly overlaps the inclined recording track last scanned (2.sub.n) and the information signal segment (field signal) recorded in the inclined recording track (2.sub.n) is then reproduced. The arrangement includes structure for determining the instantaneous relative position of the inclined reproducing track (75), in the longitudinal direction of the tape, with respect to the inclined recording track (2.sub.n), which is partly overlapped by the inclined reproducing track (75), and for generating position information (LI). The arrangement also includes structure for controlling, in dependence upon this position information (LI), the tape drive device (53) during a subsequent recording cycle.
