Patent ID: 7864635

Claim:
A recording head comprising: a semiconductor laser diode having a mirror in which a lower cladding layer, an active layer, and an upper cladding layer are laminated over a semiconductor substrate, in order, from said substrate side, and an output beam from said active layer is reflected by said mirror making at least a part or all of one edge side an inclined face, wherein said inclined face is provided to have wider skirts from said substrate side in the direction of the face opposite the substrate, and said inclined face is provided to have wider skirts along a direction of a cavity, wherein an optical waveguide is provided in a direction of a thickness of a slider and penetrating said slider in the vicinity of one edge of said slider, and an optical transducer is provided at an air bearing surface (ABS: Air Bearing Surface) of said slider, wherein the opposite face of said substrate surface of said semiconductor laser diode is fixed to an opposing face of the air bearing surface of said slider, and the optical axis of the emitting beam from said mirror is fixed so as to be substantially in agreement with the optical axis of said optical waveguide; and wherein an electrode of said semiconductor laser diode is provided on the face opposite said substrate surface, and an electric lead line is provided over the slider for supplying electric power in order to drive said semiconductor laser diode, said electrode of said semiconductor laser diode and said electric lead line provided over said slider being connected to each other.
