| 英文摘要 | A thermally assisted magnetic head includes a slider having a medium-facing surface and a surface-emitting semiconductor laser. The slider has a slider substrate on which part of the medium-facing surface is formed, and a magnetic head portion, on which another part of the medium-facing surface is formed, and which has a first surface in contact with a head stacking surface of the slider substrate, a second surface opposite the first surface, and a third surface opposite the medium-facing surface. The magnetic head portion comprises a main magnetic pole, an optical waveguide core having a first light exit surface at the medium-facing surface and a second light exit surface at the third surface, a first diffraction grating, provided in the optical waveguide core or further towards the second surface than the optical waveguide core, and a light reflective section provided further toward the first surface than the optical waveguide core. The surface-emitting semiconductor laser is provided opposing the second surface. The first diffraction grating causes part of emission light from the surface-emitting semiconductor laser to be optically coupled to the optical waveguide core. |
