A magnetic head having a plurality of read/write tracks, each track being formed of a single continuous lamina of high-permeability magnetic material which is wrapped around the edge of a support substrate and extends through an opening in the substrate. A coil encircles one leg of each of the lamina, the coils being alternately placed on opposite sides of the substrate to allow minimum space between the tracks. A magnetic gap extends less than the complete distance across each individual lamina parallel to the edge of the substrate. The electrical characteristics of each individual magnetic gap are monitored as the gap is cut. The cutting operation is terminated in accordance with the value of an electrical characteristic to obtain uniform gap characteristics for each of the gaps. The lateral position of the cut is adjusted in accordance with the value of an electrical characteristic to obtain longitudinal alignment of all of the gaps.
