Heat-assisted magnetic recording head including internal mirrors of first and second inclined surfaces
A heat-assisted magnetic recording head has an internal mirror that includes a reflecting film support body and a reflecting film. The internal mirror reflects light that comes from above a waveguide so that the reflected light travels through the waveguide toward a medium facing surface. The reflecting film support body includes first and second inclined surfaces. The reflecting film includes first and second portions that are located on the first and second inclined surfaces, respectively. The step of forming the reflecting film support body includes two-taper etching operations to be performed on an initial support body.
