Estimating the term…
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 of a flexible optical waveguide is formed in an intermediate position in the optical waveguide and in a portion fixed to the near-field optical head. Light for recording and reading information is spread within the clad. The spread light flux is reflected toward the near-field optical head by a reflective surface formed on the side of one end of the optical waveguide. The reflected light flux is collected by light-collecting structures and then is made to enter an optical minute aperture formed in the near-field optical head. Near-field light is created near the minute aperture. Light scattered by the surface of the recording medium is received. Thus, information on the recording medium can be recorded and read.
Optical information recording and reading apparatus making use of near-field light, comprising:
Optical information recording and reading apparatus as set forth in claim 5, wherein said core is formed within the beam structure supported at its both ends, the beam structure being mounted in said optical waveguide.
