Abstract:
A magnetic head in which a first magnetic core half and a second magnetic core half, each core half having a substrate with a surface obliquely angled relative to a sliding direction of the magnetic head and a magnetic metal film formed on said obliquely angled surface, are bonded together at a junction surface via a non-magnetic material for defining a magnetic gap, characterized in that:a magnetic film core defined by the magnetic metal films formed on the obliquely angled surfaces of the respective first and second magnetic core halves is positioned obliquely relative to the sliding direction of the head relative to a recording medium;the magnetic metal films formed on the obliquely angled surfaces of the respective first and second magnetic core halves are offset in a direction perpendicular to the sliding direction of the magnetic head relative to a recording medium such that the magnetic metal films formed on the obliquely angled surfaces of the respective first and second magnetic core halves are disjointed at the junction surface to the extent that a portion of each of the substrates which faces the junction surface faces a portion of the magnetic metal film formed on the obliquely angled surface of the substrate of the opposing first or second magnetic core half and which is exposed at the junction surface, each of the substrates having an exposed portion extending to the junction surface; andwherein said substrates of the respective first and second magnetic core halves are formed of a non-magnetic material.
