Abstract:
    A hologram record carrier capable of information recording or regeneration by beam irradiation, comprising a hologram recording layer storing in its interior optical interference patterns by coherent reference beam and signal beam components as a diffraction grating, and comprising a reflection functional layer superimposed on the hologram recording layer at its side opposite to beam incident side, in which nonreflecting zones are developed in irradiated regions in response to the intensity of irradiation beam.
