    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 near-field optical head has a tip end having an edge portion defined by two intersecting planes. Information recorded on a recording medium is reproduced in accordance with an intensity of scattered light of an evanescent field generated when the recording medium is illuminated with light and the tip end of the optical head is brought proximate the recording medium at an interval equal to or smaller than a wavelength of light therebetween.

    摘要: A near-field optical head applied for a head of an information recording/reading apparatus for realizing information recording and reading with high density recording medium at high speed and with reliability through interaction between a near-field light and a recording medium using a slider having a near-field optical probe. A slider (1) having a near-field optical probe is put into proximity to a recording medium (3). Further, a distance is reduced between a light emitting element (2) and a microscopic aperture (7). The microscopic aperture is controlled in protrusion amount from the recording medium (3) by a piezoelectric element. Due to this, the light intensity in the probe or light detecting section is increased to increase interaction with the recording medium (3). This realizes information recording and reading apparatus with high sensitivity and accuracy.
