HOLOGRAM RECORDING MEDIUM, HOLOGRAM RECORDING AND REPRODUCING DEVICE AND HOLOGRAM RECORDING AND REPRODUCING METHOD

摘要

PROBLEM TO BE SOLVED: To easily carry out multiple recording of holograms. SOLUTION: The hologram recording medium 1 is provided with a hologram recording medium layer for recording the holograms and a wedge substrate for changing the progression direction of incident reference light 4 and object light 5. The angle multiplex recording of the holograms is carried out by rotating the hologram recording medium 1 having the hologram recording layer and the wedge substrate, thereby changing the progression direction of the reference light 4 and the object light 5.
