ABSTRACT:
For the accurate positioning of a magnetic head to a track of a moving recording medium in a magnetic layer memory system, particularly a magnetic tape recorder, whereby a magnetic head is displaceable to different tracks in the transverse direction of the recording medium, signals are respectively recorded in tracks that are formed of two sub-tracks separate from one another by a narrow space. A write head that contains two write sub-heads separate from one another by a gap is provided for this purpose. The signals are read from the sub-tracks by two read sub-heads provided in a read head, whereby the respective read sub-heads are fashioned shorter in the transverse direction of the recording medium than the respective sub-tracks. Dependent on read signals of the two read sub-heads, the magnetic head is displaced in the transverse direction of the recording medium such that the magnetic head follows the track with optimum precision.
