ABSTRACT:
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 light20is illuminated to the recording medium10to create near-field light on a surface of the recording medium10. The created near-field light is scattered by a microscopic aperture12formed in the aperture element11so 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 aperture12and the recording medium10. Based on the distance control signal, the aperture element11is controlled in position. Due to this, the microscopic aperture12is brought into proximity to the recording medium10.
