Method of manufacturing heat-assisted magnetic recording head with internal mirror
A manufacturing method for a heat-assisted magnetic recording head includes the step of forming an internal mirror that includes a reflecting film support body and a reflecting film. 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 internal mirror includes the step of forming the reflecting film support body and the step of forming the reflecting film. The step of forming the reflecting film support body forms an initial support body, and performs two taper-etching processes on the initial support body so that the initial support body is provided with the first and second inclined surfaces.
