Abstract
A thermally-assisted magnetic head that has an air bearing surface (ABS) facing a recording medium and that performs magnetic recording while heating the recording medium includes: a magnetic recording element that includes a pole of which an edge part is positioned on the ABS and which generates magnetic flux traveling to the recording medium; a waveguide that is configured with a core through which light propagates and a cladding, surrounding a periphery of the core, at least one part of which extends to the ABS; a plasmon generator that faces a part of the core and that extends toward the ABS side; and a bank layer that is positioned between the plasmon generator and the pole, and of which an edge part on the ABS side protrudes relative to the plasmon generator.
