ABSTRACT:
A magnetic transducer head core includes two elements bonded with a non-magnetic medium sandwiched between facing surfaces of the elements. An opening for a flux inducing winding is formed in the facing surface of one of the elements adjacent the transducing surface. The opening forms an edge at a first flux gap face. A recess is formed in the facing surface of the other element adjacent the transducing surface and has an edge forming a second flux gap face of shallower depth from the transducing surface than the first face. The recess is filled with non-magnetic material; for example, copper in the case of a metal transducer head core to provide structural support for the shallower face. The pole face depth between the recess edge and transducing surface on the shallower flux gap face is then subsequently formed to a precise dimension after the elements are bonded together.
