ABSTRACT:
A hologram recording medium includes a hologram recording layer and a transparent substrate layer stacked on the hologram recording layer. The recording layer records an interference pattern of a recording beam and a reference beam. The transparent substrate layer has an inner surface facing the hologram recording layer, and this surface is formed with trace zones for guiding the recording beam and the reference beam in a prescribed guide direction. The trace zones have a higher reflectance than that of the remaining area in the inner surface of the transparent substrate layer.
