    摘要： A magnetic head includes a coil, a main pole, a write shield, and a return path section. The write shield includes a bottom shield located on the rear side in the direction of travel of a recording medium relative to the main pole. The return path section is located on the rear side in the direction of travel of the recording medium relative to the main pole and connects the bottom shield and part of the main pole away from a medium facing surface so as to define a space through which part of the coil passes. The return path section is not exposed in the medium facing surface. The bottom shield includes a base part, and a protruding part protruding from the base part toward the main pole. The base part is greater than the protruding part in length in a direction perpendicular to the medium facing surface.

    摘要： A magnetic head includes a coil, a main pole, a write shield, a gap part, and a return path section. The return path section is located on the front side in the direction of travel of a recording medium relative to the main pole, and connects the write shield and part of the main pole away from a medium facing surface to each other. The coil includes a specific coil element. The main pole has a top surface including an inclined portion and a flat portion. The write shield has an inclined surface. The inclined surface includes a first portion opposed to the inclined portion with the gap part therebetween, and a second portion located farther from the medium facing surface than the first portion. The specific coil element includes a portion interposed between the flat portion and the second portion.

    摘要： A magnetic head includes first and second coils, a main pole, a write shield, a return path section, and a yoke. The return path section is located on the front side in the direction of travel of a recording medium relative to the main pole. The yoke is located on the rear side in the direction of travel of the recording medium relative to the main pole. The first coil is wound around the main pole. The second coil is located on the rear side in the direction of travel of the recording medium relative to the main pole so as to pass between the main pole and the yoke.

    摘要： A magnetic head includes a coil, a main pole, a shield, a return path section, and an accommodation part that are disposed above the top surface of a substrate. The accommodation part accommodates at least part of the return path section. The return path section lies between the main pole and the top surface of the substrate, and connects the shield and part of the main pole away from a medium facing surface to each other so that a space through which part of the coil passes is defined. The accommodation part includes an interposer interposed between the return path section and the medium facing surface. The interposer has an inclined surface facing toward the return path section. The return path section includes an inclined portion located between part of the coil and the inclined surface and extending along the inclined surface.
