Abstract: A magnetic head comprising a pair of magnetic core halves each having a magnetic core film sandwiched between a pair of non-magnetic substrates, said magnetic core halves being abutted to each other with the end faces of the magnetic core films facing each other, with a magnetic gap being defined in an interface of abutment of said magnetic core films, wherein the magnetic core film is of a laminated magnetic film structure comprising a plurality of laminated magnetic film units laminated with insulating films in-between. Each laminated magnetic film unit in turn comprises a plurality of magnetic films with non-magnetic films in-between, with the magnetic films being magnetostatically connected to one another at film ends. By employing the laminated magnetic film unit for the magnetic core film, it becomes possible to markedly increase the magnetic permeability in a direction normal to the gap depth when anisotropy is applied in the gap depth direction.

Abstract: Each of a pair of magnetic core halves includes a substrate and a thin magnetic metal film formed on the substrate. The substrate is notched with a winding groove. The pair of the magnetic core halves are integrally bonded to each other so that a gap filling film is formed between the facing surfaces of the thin magnetic metal films. The zero depth position of the magnetic gap which is determined by the length of the facing thin magnetic metal films is offset to a magnetic recording medium sliding surface of the magnetic head from the notching start position of the winding groove on the side of the magnetic gap. Hence, the shape of the thin magnetic metal film exposed on the magnetic recording medium sliding surface is maintained constant from the initial position to the depth zero position.
