发明名称 RECORDING HEAD, METHOD OF MANUFACTURING RECORDING HEAD, AND INFORMATION RECORDING DEVICE
摘要 <p>The present invention relates to a recording head for recording information based on an optical magnetic recording system, and has an object of carrying out a high-density recording by reducing the beam diameter of an optical beam irradiated to a recording medium. When an optical beam having a larger diameter than that of the recording head is irradiated, this optical beam is condensed in a light guiding layer. The optical beam is further condensed with a sharp-headed chip. The condensed optical beam is emitted from an emission aperture smaller than the wavelength of the light at the front end of the chip, and irradiated to the recording medium. &lt;IMAGE&gt;</p>
