Abstract:
A hologram recording medium including a substrate, a hologram recording layer that records an interference pattern formed by a first wavelength beam, a wavelength selecting reflection layer provided between the substrate and the hologram recording layer that reflects the first wavelength beam and transmits a second wavelength beam, a beam absorbing layer provided between the substrate and the wavelength selecting reflection layer that absorbs the first wavelength beam, and an information layer provided between the substrate and the light absorbing layer in which information is recorded and reproduced by the second wavelength beam, a second information layer provided between the substrate and the information layer and a second wavelength selecting reflection layer provided between the information layer and the second information layer that reflects the second wavelength beam and transmits a third wavelength beam.
