The near field optical head (1000) comprises a slider (1001) supported by a suspension arm for exerting a load, receiving a floating force due to the relative motion with a recording medium, and forming a gap between the slider and the recording medium through the balance of the load and the floating force, a microstructure (1006) formed on the recording medium side of the slider (1001), a light propagating body (1803) arranged on the surface of the slider (1001) opposite to the recording medium side generally in parallel with the suspension arm, a mirror (1010) arranged generally above the microstructure (1006) in order to introduce the light from the light propagating body (1803) to the microstructure (1006), and a structure for shortening the optical path length between the output end of the light propagating body (1803) and the microstructure (1006).

摘要： An optical record and reproduce head records and reproduces information with high reliability using an optical interaction in a minute area with high-density media rotating at high speed. An optical waveguide acts to apply load to a slider (6) that receives a lift, e.g., the same system introduces light to the slider (6) and apply load to the slider (6). As a result, stabilized attitude control of the slider (6) and an increase in light intensity on the media allows recording and reproducing information with high reliability. Further, a microstructure is arranged on the edge of the slider (6) facing the media to decrease the distance to the media, thereby achieving high-density recording of information.
