摘要： In a recording apparatus for reproducing information recorded on a recording medium by utilizing near-field light, the recording apparatus realizes reliable information reproduction with a simple structure. Illumination light 20 is illuminated to the recording medium 10 to create near-field light on a surface of the recording medium 10. The created near-field light is scattered by a microscopic aperture 12 formed in the aperture element 11 so that scattering light (propagation light) thereof is detected to create a reproduced signal. Derived from the created reproduced light a distance control signal representative of a distance between the microscopic aperture 12 and the recording medium 10. Based on the distance control signal, the aperture element 11 is controlled in position. Due to this, the microscopic aperture 12 is brought into proximity to the recording medium 10.

摘要： A recording medium for recording and reproducing information utilizing near field light has a transparent substrate and a data mark arrangement layer disposed over a surface of the transparent substrate. A metal particulate is dispersed only in the data mark arrangement layer so that a surface plasma is generated upon interaction of the data mark arrangement layer with near field light generated by incident light or irradiating light to thereby amplify the intensity of scattered light generated as a result of the interaction between the data mark arrangement layer and the near field light.

Brought into proximity to a recording medium (3) is a near-field optical head (101) having a slider (31) formed with an inverted cone formed hole such that an apex thereof is rendered as a microscopic aperture (6). A microscopic electrode (5) is formed on a side surface (32) of the inverted cone formed hole. An electric field (9) is applied only to a microscopic region to cause light emission. It is possible at the aperture (6) to detect a light emitted only by the microscopic region.
