    • 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.

    • A magnetic layer for writing incorporates: a pole layer having an end face located in a medium facing surface; and an upper yoke layer. A first magnetic layer for flux concentration is connected to the pole layer at a location away from the medium facing surface, and allows a magnetic flux corresponding to a magnetic field generated by a first coil to pass. A second magnetic layer for flux concentration is connected to the upper yoke layer at a location away from the medium facing surface, and allows a magnetic flux corresponding to a magnetic field generated by a second coil to pass. When seen in the direction orthogonal to the interface between the second magnetic layer and the upper yoke layer, this interface is disposed at a location that does not coincide with the interface between the first magnetic layer and the pole layer.
    • 用于写入的磁性层包括:具有位于介质面向表面中的端面的极层; 和上轭铁层。 用于焊剂浓度的第一磁性层在远离介质相对表面的位置处连接到极层,并且允许对应于由第一线圈产生的磁场的磁通通过。 用于磁通集中的第二磁性层在远离介质相对表面的位置处连接到上磁轭层,并且允许对应于由第二线圈产生的磁场的磁通通过。 当在与第二磁性层和上磁轭层之间的界面正交的方向上观察时,该界面设置在与第一磁性层和极层之间的界面不一致的位置。
