Abstract:
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.
