ABSTRACT:
A near field light generating device generating near field light from incident light by using a solid immersion mirror and a heat assisted magnetic recording head with the same are provided. The near field light generating device includes a light source; a waveguide core which transmits light; and a solid immersion mirror, which generates near field light, including an upper transmission surface through which light from the waveguide core is transmitted into the solid immersion mirror, a lower reflection surface, opposite the upper transmission surface, which reflections light incident thereon, lateral reflection surfaces, facing each other at sides of the solid immersion mirror, which reflect light incident thereon, and a lower transmission region disposed at a center of the lower reflection surface. Light reflected from the lateral reflection surfaces forms a light spot on the lower transmission region.
