Heat-assisted magnetic recording head with laser diode fixed to slider
A heat-assisted magnetic recording head includes a slider, an edge-emitting laser diode fixed to the slider, and an external mirror fixed to the laser diode. 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.
