摘要： A composite type thin-film magnetic head. In one embodiment, a substrate is used as a base, and an insulating film, a lower shielding magnetic film, a magneto-resistive element, an upper shielding magnetic film, a magnetic gap film, a recording inductive magnetic film and a protective layer are laminated on this base. An inductive head used for recording is formed by the upper shielding magnetic film. A magnetic gap film, a recording inductive magnetic film, and a magneto-resistive head used for playback are formed by the magneto-resistive element. The upper shielding magnetic film and recording inductive magnetic film are formed by an electroplating of permalloy. The upper shielding magnetic film has a lower nickel concentration on the side of the magnetic gap film than on the side of the magneto-resistive element.

摘要： A compound thin film magnetic head in which the upper shield of the readout MR head also serves as the lower magnetic film of the write inductive head. The upper shield has a layered structure including a shield part of soft magnetic material functioning as a shield to magnetically shield the MR head, a lower pole part and transition part of soft magnetic material functioning as a write magnetic pole opposing the upper pole of the inductive head, and a nonmagnetic separation layer to magnetically separate these. Between the lower pole part and the transition part, an additional nonmagnetic separation layer can be provided. The shield part can be configured from multiple magnetic films formed in layers and enclosing a nonmagnetic separation layer.
