The head comprises a plurality of magnetic head elements each including a magnetic record/playback pole disposed opposite to the surface of the medium and a flux conducting pole disposed opposite to a lateral end face of the medium. The elements are arranged so that the individual record/playback poles define different tracks across the width of the medium.
