PROBLEM TO BE SOLVED: To provide a high-density optical storage device which performs recording density exceeding the limit of a light diffraction. SOLUTION: A semiconductor laser 1 which is a light source, an objective lens 5 for converging a light and a reflector element 6 arranged adjacent to the surface of a recording medium 7 for reflecting a part of the light converged by the objective lens are provided. The light converged by the objective lens 5 is radiated to the boundary between the reflector element 6 and the recording medium 7. |
