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.

    摘要： A magnetic layer for writing incorporates: a pole layer having an end face located in a medium facing surface; and an upper yoke layer. A first magnetic layer for flux concentration is connected to the pole layer at a location away from the medium facing surface, and passes a magnetic flux corresponding to a magnetic field generated by a first coil. A second magnetic layer for flux concentration is connected to the upper yoke layer at a location away from the medium facing surface, and passes a magnetic flux corresponding to a magnetic field generated by a second coil. A nonmagnetic layer is disposed between the pole layer and the upper yoke layer. The upper yoke layer is connected to the pole layer at a location closer to the medium facing surface than the nonmagnetic layer.
