    摘要: A magnetic head includes a coil, a main pole, a write shield, and first and second yoke layers. The first and second yoke layers are magnetically connected to the write shield and aligned along the direction of travel of a recording medium such that the main pole is interposed therebetween. The coil includes a winding portion of planar spiral shape that is formed in one or more layers. The magnetic head further includes: a first coupling part located away from the medium facing surface and magnetically coupling the main pole and the second yoke layer to each other; and a second coupling part located away from the medium facing surface and magnetically coupling the first yoke layer and the second yoke layer to each other without touching the main pole. The winding portion is wound around the first coupling part, and a part of the winding portion passes between the first and second coupling parts.

    摘要: A magnetic head includes: a coil; a main pole; a first shield disposed backward of the main pole along a direction of travel of a recording medium; a first return path section connecting the first shield to the main pole; a second shield disposed forward of the main pole along the direction of travel of the recording medium; and a second return path section connecting the second shield to the main pole. An interface between the first return path section and the main pole has an end closest to a medium facing surface, and an interface between the second return path section and the main pole has an end closest to the medium facing surface, the latter being closer to the medium facing surface than the former. The second return path section includes a yoke layer located away from the medium facing surface and in contact with the main pole. The coil includes at least one coil element that passes between the second shield and the yoke layer.

    摘要: A magnetic head includes a magnetic structure incorporating a write shield. The magnetic structure is formed to include a first magnetic layer, a second magnetic layer stacked on the first magnetic layer, and a seed layer. The first magnetic layer has a front end face located in the medium facing surface and a top surface. The second magnetic layer has a front end face located in the medium facing surface and a bottom surface. The top surface of the first magnetic layer includes a first region including an end located in the medium facing surface and a second region farther from the medium facing surface than the first region. The seed layer is not present on the first region of the top surface of the first magnetic layer but is present on the second region.

    摘要: A magnetic head includes a coil, a main pole, a gap part, a write shield, and a return path section. The return path section includes a yoke part and first and second coupling layers. The first coupling layer is connected to the write shield. The second coupling layer magnetically couples the first coupling layer to the yoke part, and has an end face facing toward a medium facing surface and located away from the medium facing surface. The coil includes a first coil element and a plurality of second coil elements that each extend to pass through a space defined by the main pole, the gap part, the write shield, and the return path section. The first coil element is disposed with the first coupling layer interposed between the medium facing surface and the first coil element. The second coil elements are disposed with the second coupling layer interposed between the medium facing surface and the second coil elements, and with the first coil element interposed between the main pole and the second coil elements. The second coil elements are aligned perpendicularly to the medium facing surface.

    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 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.
