Abstract:
1. A thin-film magnetic head constructed such that a main magnetic pole layer having a magnetic pole end face on a side of a medium-opposing surface opposing a recording medium, a write shield layer opposing the main magnetic pole layer in the medium-opposing surface, a gap layer formed between the main magnetic pole layer and write shield layer, and a thin-film coil wound around one or more of the main magnetic pole layer, the write shield layer or a shield magnetic layer connected to the main magnetic pole layer are laminated on a substrate; wherein the write shield layer comprises an opposing shield part opposing the main magnetic pole layer in the medium-opposing surface, and a front shield part connected to the opposing shield part without straddling the thin-film coil and disposed on the medium-opposing surface side of the thin-film coil, and wherein the front shield part comprises a shield front end face disposed in the medium-opposing surface, a shield upper end face disposed at a position distanced more from the substrate than is the shield front end face and formed along an intersecting direction intersecting the medium-opposing surface and distanced from the medium-opposing surface, and a shield connecting part directly connecting the shield front end face to the shield upper end face.
