    摘要： A main pole has a front end face including a first end face portion and a second end face portion. A plasmon generator has a near-field light generating surface. A surrounding layer has a first surrounding layer end face and a second surrounding layer end face located on opposite sides of the first end face portion in the track width direction. A gap film has a first gap film end face and a second gap film end face located on opposite sides of the near-field light generating surface in the track width direction. Each of the first and second gap film end faces includes a portion located between the first and second surrounding layer end faces, but does not include any portion interposed between the first surrounding layer end face and the first end face portion or between the second surrounding layer end face and the first end face portion.

    摘要： A return path section includes first and second yoke portions and first, second and third columnar portions. The first and second yoke portions and the first columnar portion are located on the front side in the direction of travel of a recording medium relative to a waveguide core. The second and third columnar portions are located on opposite sides of a plasmon generator and connected to a shield. The first yoke portion connects a main pole to the first columnar portion. The second yoke portion connects the first columnar portion to the second and third columnar portions. A coil is wound around the first columnar portion. A heater and an expansion layer are located on the rear side in the direction of travel of the recording medium relative to the core.

    摘要： A magnetic head includes a medium facing surface, a read head unit, a write head unit, and a protrusion device. The protrusion device causes part of the medium facing surface to protrude toward a recording medium. The read head unit has a first end face located in the medium facing surface and includes a first contact sensor for detecting contact of the first end face with the recording medium. The write head unit has a second end face located in the medium facing surface and includes a second contact sensor for detecting contact of the second end face with the recording medium. The first end face and the second end face are located at positions different from each other in a direction of travel of the recording medium.
