<p>A recording apparatus that uses near-field light to reproduce information recorded on a recording medium and realizes highly reliable information reproduction by means of a simplified structure. A recording medium (10) is irradiated with light (20) so that near-field light may present on the surface of the recording medium (10). The near-field light is scattered by a minute hole (12) in a perforated device (11), and the scattered light (propagating light) is detected to reproduce a signal. The reproduced signal is used to provide a distance control signal that indicates the distance between the minute hole (12) and the recording medium (10). The position of the perforated device (11) is controlled by the distance control signal, and the minute hole (12) is thus allowed to approach the recording medium (10).</p> |
