THIN-FILM MAGNETIC HEAD, METHOD OF MANUFACTURING THE SAME, HEAD GIMBAL ASSEMBLY, AND HARD DISK DRIVE

摘要

A thin-film magnetic head is constructed such that a main magnetic pole layer, a write shield layer, a gap layer, and a thin-film coil are laminated on a substrate. The thin-film magnetic head has a leading shield part opposing the main magnetic pole layer on the substrate side of the main magnetic pole layer. The thin-film magnetic head has a substrate side coil layer disposed between the main magnetic pole layer and the substrate. In the thin-film magnetic head, a space between a lower end face of the leading shield part and the substrate and a space between an upper end face in the substrate side coil layer and the substrate are formed equal to each other.
