Patent ID: 8395972

Claim:
A thermally assisted magnetic head comprising: a slider having a medium-opposing surface opposing a magnetic recording medium, the slider including: a slider substrate including a light source placing surface that intersects with the medium-opposing surface; a magnetic head part including a recording head that records data on the magnetic recording medium and an optical waveguide that guides a laser light emitted from a laser diode to the medium-opposing surface side; and a light source mounting part formed on the light source placing surface, the light source mounting part including a bottom part for receiving a placing part of the laser diode to be placed on the light source placing surface, and a wall part formed along an edge portion of the bottom part; and the laser diode that emits the laser light, the laser diode mounted on the light source mounting part such that the emitting part and the incident part are opposed to each other, wherein the wall part has an incident part of the optical waveguide on which the laser light is incident formed at a corresponding position corresponding to an emitting part of the laser diode from which the laser light is emitted.
