    Abstract: 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 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.

    Abstract: A magnetic head includes: a main pole; a coil; a first shield having an end face that is located in a medium facing surface at a position forward of an end face of the main pole along a direction of travel of a recording medium; and a first return path section disposed forward of the main pole along the direction of travel of the recording medium. The first return path section connects part of the main pole away from the medium facing surface to the first shield so that a first space is defined. The coil includes a first portion having a planar spiral shape and wound around a core part of the first return path section. The first portion includes first and second coil elements that each extend through the first space. No part of the coil other than the first and second coil elements exists in the first space.
