Abstract
A thermally-assisted magnetic recording head includes a medium facing surface, a magnetic pole, a waveguide including a core and a cladding, and a plasmon generator. The magnetic pole is located forward of the core in the direction of travel of a magnetic recording medium. The plasmon generator is disposed between the core and the magnetic pole. The core has an evanescent light generating surface facing toward the plasmon generator. The plasmon generator has a front end face located in the medium facing surface, a flat surface facing toward the'evanescent light generating surface, and first and second side surfaces that are at a distance from each other and are located farther from the evanescent light generating surface than is the flat surface.
