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： The invention is directed to improvement of a write element of a thin film magnetic head. In the write element, a first coil and a second coil are provided on a first insulating film formed on one surface of a first magnetic film and surround in a spiral form a back gap portion. A second yoke portion in the upper position comprises a wide portion, a narrow portion and a sloping flare portion. The wide portion has a flat surface and is connected to the first magnetic film by a back gap portion at the rear of the medium-facing surface. The narrow portion forms the second pole portion and the surface of the narrow portion being at a lower position than the surface of the wide portion. The sloping flare portion extends from the narrow portion to the wide portion, gradually increasing in width and its surface sloping upward away from the surface of the narrow portion to the surface of the wide portion.
