Patent ID: 7463450

Claim:
A thin film magnetic head comprising: a main magnetic pole film; a write shield film; an upper yoke magnetic pole film; and a thin film coil, wherein the main magnetic pole film has a magnetic pole end portion on a medium opposing surface side which should face a magnetic disk, the write shield film faces the magnetic pole end portion so as to form a recording gap film on the medium opposing surface side, the upper yoke magnetic pole film is provided on the side of the main magnetic pole film close to the write shield film, and the end portion of the upper yoke magnetic pole on the medium opposing surface side is retracted in a direction apart from the medium opposing surface in accordance with an increase in film thickness which is measured from the surface of the main magnetic pole film, the thin film coil supplies a magnetic flux passing through the main magnetic pole film, the write shield film and the upper yoke magnetic pole film, the write shield film comprises a first write shield portion and a second write shield portion, the first write shield portion faces the magnetic pole end portion of the main magnetic pole film with the recording gap film therebetween in the medium opposing surface, and is formed so that a throat height is determined based on the depth in a direction crossing the medium opposing surface, and has an end surface formed to have the same height as that of the end surface of the upper yoke magnetic pole film on the side close to the thin film coil, and the second write shield portion is connected with the end surface of the first write shield portion.
