A method for a definitive fixing of the breadth of magnetic layers in the vicinity of the end face of a recording carrier, which breadth determines the track breadth, in which an integrated magnetic head structure is carried on a substrate and has a large number of thin magnetic, non-magnetic, insulating and electrically conductive layers stacked one upon an another, and in which originally broader magnetic layers are partially worn down by ion bombardment, the zones not to be worn down being first covered with a mask. Ion bombardment is carried out at right angles to the thin layers, i.e. at right angles to the plane of the substrate, with the mask suitably disposed. |
