MAGNETIC HEAD AND ITS MANUFACTURE

摘要

The reliability of a magnetic head is improved by eliminating the need of putting glass, etc., on a magnetic film. A method of manufacturing a magnetic head which has a pair of magnetic core halves in which magnetic films are formed on substrates and which face to each other and a thin film coil is formed on at least one of the mutually facing surfaces of the core halves, comprising the steps of forming recessed portions in the substrates by, say, ion milling, and forming the magnetic films in the recessed sections. It is preferable that the magnetic films each comprise a magnetic film whose axis of easy magnetization is in the direction of the magnetic gap depth and a magnetic film whose axis of easy magnetization is in the direction perpendicular to the depth direction.
