| 英文摘要 | To provide an information recording and reproducing apparatus for supplying light for generating near-field light to a near-field light head, generating a sufficiently large amount of near-field light at a vicinity of a very small opening and realizing reproduction and recording with ultra high resolution, recording and reproduction at high speed and high SN ratio formation, in an information recording and reproducing apparatus constituted by a record medium 107, a light source 101, a suspension arm 109, a flexure 110 fixed to the suspension arm 109, a near-field light head 301 fixed to the flexure 110 and having a very small opening on a side of the record medium 107, a light guiding structure 103 for guiding light flux from the light source 101 to the near-field light head 301 and a light receiving portion 108, the very small opening and an optical wave guide for guiding light to the very small opening are disposed on the same side of the near-field light head and the light guiding structure is constituted by an optical propagating portion fixed to the suspension arm, an optical coupling portion fixed to the near-field light head and an optical connecting portion for optically connecting the optical propagating portion and the optical coupling portions. |
