摘要： Provided is a light source unit that is to be joined to a slider to form a thermally-assisted magnetic recording head. The light source unit comprises: a unit substrate having a source-installation surface; a light source provided in the source-installation surface and emitting thermal-assist light; and a photodetector bonded to a rear joining surface of the unit substrate in such a manner that a rear light-emission center of the light source is covered with a light-receiving surface of the photodetector. The photodetector can be sufficiently close to the light source; thus, constant feedback adjustment with high efficiency for the light output of the light source can be performed. This adjustment enables light output from the light source to be controlled in response to changes in light output due to surroundings and to changes with time to stabilize the intensity of light with which a magnetic recording medium is irradiated.

摘要： A thermally assisted magnetic head which can realize high-density writing onto magnetic recording media is provided.The thermally assisted magnetic head includes a magnetic head part having a medium-opposing surface and a back face opposing the medium-opposing surface. The magnetic head part has a recording head part, an optical waveguide, and light shields. The optical waveguide extends along the opposing direction of the medium-opposing surface and back face. Each of the light shields extends along the opposing direction of the medium-opposing surface and back face and inhibits laser light from passing between the medium-opposing surface and back face. The optical waveguide and light shields are arranged on a first line when seen from the back face. When seen from the back face, the light shields oppose each other while interposing the first line therebetween and are arranged on a second line substantially orthogonal to the first line.

摘要： A near-field light generator plate 36 of the present invention is arranged to face a medium 10, and one portion 36b and other portion 36a in a medium-facing surface S thereof are made of their respective electroconductive materials different from each other. Since the one portion and the other portion in the medium-facing surface are made of the electroconductive materials different from each other, this medium-facing surface is formed by a surface removing step such as polishing or etching from the medium-facing surface side so that a difference between heights of the one portion and the other portion is readily made based on the difference of the materials.
