摘要： It is an optical information recording and reading apparatus for recording and/or reading information at a high density by using a near-field light-generating device as a near-field optical head. The end surface of the core 201 of a flexible optical waveguide 103 is formed in an intermediate position in the optical waveguide 103 and in a portion fixed to the near-field optical head 104. Light for recording and reading information is spread within the clad 202. The spread light flux is reflected toward the near-field optical head 104 by a reflective surface 203 formed on the side of one end of the optical waveguide 103. The reflected light flux is collected by light-collecting structures and then is made to enter an optical minute aperture 206 formed in the near-field optical head 104. Near-field light is created near the minute aperture 206. Light scattered by the surface of the recording medium 105 is received. Thus, information on the recording medium 105 can be recorded and read.

摘要： The invention concerns a recording apparatus for reproducing information recorded on a recording medium by utilising near-field light. The recording apparatus comprises: an aperture element having a microscopic aperture to scatter near-field light; a light illuminating means for introducing illumination light to the recording medium such that near-field light is created on a surface of the recording medium, the illumination light comprising two different modulation frequencies; a first light detecting means for detecting first propagation light caused by the microscopic aperture scattering the near-field light having one of the two modulation frequencies, and for converting the detected first propagation light into a reproduced signal; a second light detecting means for detecting second propagation light caused by the microscopic aperture scattering the near-field light having the other of the two modulation frequencies, and for converting the detected second propagation light into a control signal; and a control means for controlling a spacing between the aperture element and the recording medium based on the control signal.
