    摘要: A near-field optical head for an information recorder/reader, for recording/reading information on/from a high-density recording medium at high speed and with high reliability by causing interaction between near-field light and the recording medium by means of a slider having a near-field light probe. A slider (1) having a near-field light probe is provided close to a recording medium (3), and the distance between the light-emitting device (2) and a small opening (7) is short. The amount of projection of the small opening from the recording medium (3) is controlled by a piezoelectric device. As a result the intensity of light at the probe or at a photodetecting section is increased, and the interaction with the recording medium (3) is enhanced. Thus, an accurate information recorder/reader with high sensitivity is realized.

    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.

    摘要: 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).

    摘要: An information recording medium and an information reproducing apparatus capable of performing information reproduction and tracking control by using near-field light. A projecting data bit (12) having a triangular cross-section perpendicular to the direction of the track is formed as an information unit on an information recording medium (3). Near-field light produced by a reproduction probe (1) is scattered with a directivity by the slants of the data bit (12), and the reflected and scattered light is detected by reproduction photodetectors (6, 7) arranged symmetrically on both sides of the center axis of the reproduction probe (1) along the track. The detection signal is converted to a differential signal by a differential circuit (20) and the outputted differential signal drives an actuator (22) through a tracking signal generating circuit (21), and the position of the reproduction probe (1) is controlled for tracking control.
