Abstract:
A thermally-assisted magnetic recording head includes: a main pole having an end face located in a medium facing surface; a waveguide; a plasmon generator having a near-field light generating part located in the medium facing surface; and a shield located on the rear side in the direction of travel of a recording medium with respect to the main pole. The shield has an end face located in the medium facing surface and lying on the rear side in the direction of travel of the recording medium with respect to the end face of the main pole. The end face of the main pole and the end face of the shield are at a distance of 50 to 300 nm from each other. The near-field light generating part is located between the end face of the main pole and the end face of the shield in the medium facing surface.
