ABSTRACT:
A multitrack magnetic head is made from an electrically conductive first helix formed on an iron wire that is, in turn, wound to form a second helix. By cutting or lapping a longitudinal flat along one side of the second helix, the first helix is severed into respective discrete coil-wound gapped cores.
