    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, a substrate side shield part has contact with the leading shield part. The thin-film coil has a substrate side coil layer between the main magnetic pole layer and substrate. 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. The depth of the leading shield part is formed to be smaller than the depth of the substrate side shield part.

    摘要： A magnetic head includes first and second coils, a main pole, a write shield, a return path section, and a core part. The return path section includes a yoke part magnetically connected to the write shield, and a coupling part located away from a medium facing surface and magnetically coupling the yoke part and the main pole to each other. The first coil is located on the front side in the direction of travel of a recording medium relative to the main pole and wound around the coupling part. The core part is located farther from the medium facing surface than is the coupling part, and is magnetically connected to the main pole. The second coil is located on the front side in the direction of travel of the recording medium relative to the main pole and wound around the core part.
