HOLOGRAM RECORDING MEDIUM, HOLOGRAM RECORDING DEVICE AND METHOD

摘要

A hologram recording medium (1) comprising a hologram recording layer (3) consisting of a photopolymer layer and formed on a substrate (2) consisting of a colorless, transparent resin film or the like, and a protection layer (4) consisting of a colorless, transparent resin film or the like and formed on the hologram recording layer (3), wherein the substrate (2) and the protection layer (4) are formed of a low-double- refraction material, and an optical axis of double refraction in the case of a strip-form medium is set to agree with a longer-side direction or a shorter-side direction thereof.
