The pole layer has an end face located in a medium facing surface, the end face having a first portion and a second portion that is located farther from a substrate than the first portion and connected to the first portion. The first portion has a width that decreases as the distance from the substrate decreases. The second portion has a uniform width that defines the track width. In the medium facing surface, the nonmagnetic metal layer exists on both sides of the second portion, the sides being opposed to each other in the direction of track width.

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.
