Abstract: A multitrack magnetic head is made from an electrically conductive first helix (10) formed on an iron wire (12) that is, in turn, wound about a mandrel (14) to form a second helix (15). By longitudinally cutting along one side of the second helix, discrete core pieces are formed, each having a helical winding (i.e. a portion of the first helix) wrapped thereabout.
