Thin-film magnetic head, method of manufacturing the same, head gimbal assembly, and hard disk drive
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, a substrate side shield part comes in contact with the leading shield part. The thin-film coil has a substrate side coil layer disposed between the main magnetic pole layer and the substrate. In the thin-film magnetic head, the spaces to the substrate about a leading lower end face of the leading shield part, a shield upper end face of the substrate side shield part, and coil upper end face of the substrate side coil layer are formed to be equal to each other. Further, a depth of the leading shield part is formed to be small than the depth of the substrate side shield part.
