Abstract:
A thin film magnetic head comprising:a functional film having a magnetic transducer function; a first gap film and a second gap film sandwiching the functional film in between, the first and second gap films each having electrical insulating properties: and a first shield layer and a second shield layer sandwiching the functional film with the first and second gap films in between, respectively, so as to prevent an undesired magnetic field from reaching to the functional film, wherein at least one of the first and second shield layers includes an inner layer having a controlled direction of magnetization, a magnetization stabilizing layer controlling the direction of magnetization of the inner layer and an outer layer having a freely changeable direction of magnetization, laminated in order from the functional film, and wherein an intermediate layer is provided between the magnetization stabilizing layer and the outer layer.
