摘要： A thin film magnetic head has a configuration in which a main magnetic pole film having a magnetic pole end portion on a medium opposing surface (ABS) side facing a magnetic disk, a write shield film facing the magnetic pole end portion so as to form a recording gap film on the medium opposing surface side, and a thin film coil wound around at least a part of the write shield film are laminated. Further, the thin film magnetic head has an upper yoke magnetic pole film whose size is larger than that of the main magnetic pole film at a part more distant from the ABS than the recording gap film, and this upper yoke magnetic pole film is bonded to the side of the main magnetic pole film close to the thin film coil. In the upper yoke magnetic pole film, an end portion on the ABS side is retracted in a direction apart from the ABS in accordance with an increase in film thickness which is measured from the surface of the main magnetic pole film.

摘要： A slider comprises a substrate, a thin-film magnetic head element, an insulating portion, and a medium facing layer. The substrate has a first surface facing toward a recording medium and a second surface meeting this first surface. The first surface is located farther from the recording medium than an air bearing surface. The thin-film magnetic head element is located near the second surface of the substrate and near the air bearing surface. The insulating portion surrounds the thin-film magnetic head element and has a surface constituting a part of the air bearing surface. The medium facing layer is adjacent to the first surface of the substrate and has a surface constituting another part of the air bearing surface. The substrate has a hardness greater than that of the insulating portion. As the substrate and the medium facing layer are compared in hardness, the medium facing layer has a hardness closer to that of the insulating portion.
