Thermally-assisted magnetic recording head having a plasmon generator
A plasmon generator has a near-field light generating part located between an end face of a main pole located in a medium facing surface and an end face of a shield located in the medium facing surface. A waveguide has a core having a front end face facing toward the medium facing surface. The front end face has first and second end portions located at opposite ends in the direction of travel of a recording medium. The first end portion is located closer to the near-field light generating part than is the second end portion. Either a main pole or a shield overlaps only a region of the front end face of the core when viewed in a direction perpendicular to the medium facing surface, the region extending from a midpoint position between the first and second end portions to the first end portion.
