Abstract: A magnetic head reads and writes a plurality of information tracks, recorded as magnetization patterns on a magnetic recording medium, with two magnetic sheets mounted in a supporting frame. Complementary sheets each define a number of alternating three-sided and two-sided figures aligned along a subsequently formed head face. A gap-forming non-magnetic material is placed along one leg of each figure on one of the sheets, and the sheets are placed together, welded, encapsulated and ground to form a head. Preformed windings slip over one leg of each of the three-sided figures and preformed shielding cans surround the magnetic elements.
