    • PROBLEM TO BE SOLVED: To provide an inexpensive information recording and reproducing device which prevents increasing of the number of parts while efficiently guiding the luminous flux from a light source to a microstructure, such as an opening, lightens the mass of a near-field optical head, forms the stronger near-field light near the microstructure and realizes recording and reproducing of information at an ultra-high density and high speed at which high-speed tracking is performed. SOLUTION: This information recording and reproducing device comprises the light source, the near-field optical head formed with the microstructure, an optical waveguide having a core and clad, a photodetecting section and a recording medium and uses the near-field light, in which the near-field optical head is formed with a lens mechanism on the surface different from the surface formed with the microstructure and the optical waveguide is formed with a core end face in mid-way of the optical waveguide and is formed with at least a first reflective surface and a second reflective surface.
    • 要解决的问题:为了提供一种廉价的信息记录和再现装置,其防止部件数量的增加,同时有效地将来自光源的光通量引导到例如开口的微结构,减轻近场光学的质量 头部在微结构附近形成更强的近场光,并以实现高速跟踪的超高密度和高速度实现信息的记录和再现。 解决方案:该信息记录和再现装置包括光源,形成有微结构的近场光学头,具有芯和包层的光波导,光电检测部分和记录介质,并使用近场光,其中 近场光学头在与微结构形成的表面不同的表面上形成透镜机构,并且光波导在光波导的中途形成有芯端面,并且形成有至少第一 反射表面和第二反射表面。
