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 having a write shield end face disposed 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 any of the main magnetic pole layer, the write shield layer or a shield magnetic layer connected the main magnetic pole layer are laminated on a substrate; wherein the shield magnetic layer comprises a lower front shield part disposed on the substrate side of the main magnetic pole layer and disposed on the medium-opposing surface side of the thin-film coil, and a front end angle representing an angle formed between a front end face disposed in the medium-opposing surface of the lower front shield part and a lower end face connected to the front end face and disposed at a position closest to the substrate in the lower front shield part is set at an obtuse angle.
