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 and near-field optical probe utilizing near-field light to achieve high density of information recording and hence enhance resolution in reproducing. A phase shift arrangement layer is formed arranged alternately with a phase shifter region to cause shift by 180 degrees in incident light and a transmission region transparent for a wavelength of the incident light. Furthermore, a row of data marks are arranged in a position above the phase shifter regions and transmission region. Due to this, cancellation is made between spread of near-field light due to incident light transmitted through the phase shifter region and spread of near-field light due to incident light transmitted through the transmission region, providing sharpness in an intensity distribution of near-field light over the data mark. Also, a phase shifter is provided at a through-hole of the near-field optical probe, enabling to produce more localized near-field light.

摘要： An information reproducing apparatus has a medium with a linear tracking mark extending in a scanning direction and a linear data mark extending in a direction orthogonal to the scanning direction. A light control unit irradiates the data mark with a first near-field light polarized in the scanning direction and irradiates the tracking mark with a second near-field light polarized in the direction orthogonal to the scanning direction. A detector detects light scattered by the data mark and the tracking mark irradiated with the first near-field light and the second near-field light, respectively. A signal processing unit processes a first output signal from the detector corresponding to the detected light scattered by the data mark and processes a second output signal from the detector corresponding to the detected light scattered by the tracking mark. The signal processing unit has a control circuit that carries out tracking control in accordance with an intensity of the second output signal and that carries out access control in accordance with an intensity of the first output signal.
