Abstract
A thermally-assisted magnetic recording head includes a medium facing surface, a main pole, a waveguide, and a plasmon generator. The plasmon generator includes a first metal layer and a second metal layer. The first metal layer includes a plasmon exciting portion on which surface plasmons are excited. The second metal layer is located on the first metal layer, and includes a bottom surface in contact with the first metal layer, a top surface located on a side opposite to the bottom surface, a front end face that is located in the medium facing surface and generates near-field light from the surface plasmons, and a connecting surface that connects the top surface and the front end face. The connecting surface includes an inclined portion inclined relative to a direction perpendicular to the medium facing surface.
