The write shield layer has an opposing shield part opposing the main magnetic pole layer and a front shield part. The front shield part is connected to the opposing shield part without straddling the thin-film coil. Besides, the front shield part has a shield front end face disposed in the medium-opposing surface and a shield upper end face formed distanced from the medium-opposing surface. Further, the front shield part has a shield connecting part. The shield front end face is connected to the shield upper end face by the shield connecting part."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Perpendicular magnetic recording head including a front shield part and the method of manufacturing the same","description":"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.
