摘要：
The thermally-assisted magnetic recording head includes: a laser light source having an emission surface, the emission surface allowing laser light to be emitted therefrom; a waveguide having a core and a cladding, the core allowing the laser light emitted from the laser light source to propagate therethrough, and the cladding surrounding the core; a magnetic pole; and a plasmon generator. Each of the core and the cladding has an end surface facing the emission surface, and the end surface of the cladding suppresses returning of the laser light to the laser light source.
