Abstract
For accurate positioning of a transducer to a track of a tape-recording medium, for example a magnetic head to a magnetic tape, a sensing device is utilized which is partially covered by the edge of the recording medium and comprises a light barrier structure. In the first embodiment, the light barrier structure is fixed at a control signal generated by way of a converter is supplied to a positioning device for the transducer. Dependent on the control signal, the transducer is positioned such that the write and read elements thereof respectively have a prescribed distance from the edge of the recording medium. In a second embodiment, at least one part of the light barrier is disposed at the transducer 4 and extends in the region of the transducer 4 to a region which corresponds to the stroke of the positioning of the transducer when the same is positioned to different tracks.
