摘要:
It is an objective that the optical loss and the number of optical components are reduced in an optical recording head using a near-field where a laser beam is guided from a light source to the tip of the head and a thermally assisted magnetic recording head. A structure where the traveling direction of emitted beam is rotated in the direction of the cavity of the laser diode element and a reflector for guiding the beam to the surface of the surface of the laser diode element is monolithically integrated in the laser diode element is mounted over the slider so that the direction of the cavity of the laser diode element is parallel to the surface of the recording medium, and the substrate side of the laser diode element is mounted to be in the direction opposite the face adjacent to the upper face of the slider.
