摘要： A thermally assisted magnetic head includes a main magnetic pole layer, a near-field light generating layer having a generating end part generating near-field light arranged within a medium-opposing surface, and an optical waveguide guiding light to the near-field light generating layer. The thermally assisted magnetic head includes a base layer which a base groove part having a width gradually getting smaller along a depth direction and extending in an intersecting direction intersecting with the medium-opposing surface is formed. The near-field light generating layer has an in-groove generating layer formed inside of the base groove part. The in-groove generating layer is formed along an inner wall surface of the base groove part and has a thin-film like structure.

The laser diode has an emitting end face that includes an emission part for emitting laser light; a mounting surface that lies at an end in a direction perpendicular to the plane of an active layer and faces the slider; and a rear surface opposite to the mounting surface. The external mirror includes: a first to-be-fixed part disposed along the emitting end face; a second to-be-fixed part disposed along the rear surface; and a coupling part that couples the first and second to-be-fixed parts to each other. The first to-be-fixed part has a reflecting surface that reflects the laser light emitted from the emission part toward the waveguide.
