PROBLEM TO BE SOLVED: To provide a heat-assisted magnetic recording head that allows easy alignment of laser light with a waveguide while using an edge-emitting laser diode as the light source for emitting light that is used for generating near-field light. SOLUTION: A heat-assisted magnetic recording head 200 includes a slider 201, an edge-emitting laser diode 202 fixed to the slider 201, and an external mirror 203 provided outside the slider 201. The slider 201 includes a magnetic pole, a waveguide, a near-field light generating element, and a substrate. The laser diode 202 includes: an active layer; an emitting end face that lies at an end in a direction parallel to the plane of the active layer and includes an emission part for emitting laser light; and a bottom surface that lies at an end in a direction perpendicular to the plane of the active layer. The laser diode is arranged so that the bottom surface faces the top surface 201c of the slider 201. The external mirror 203 reflects the laser light emitted from the emission part toward the waveguide. COPYRIGHT: (C)2011,JPO&INPIT |
