| 摘要 |
The present invention provides a holographic recording medium comprising: an optical recording layer, which optical recording layer includes one of a polymer compound having photoisomerizable groups in the side chain thereof and a polymer compound in which photoisomerizable molecules are dispersed therein, which recording layer records a hologram by having optical anisotropy induced by irradiation with a writing light having a predetermined wavelength thereon; and an optical filter layer formed on at least one side of the optical recording layer, which optical filter layer allows transmission of the writing light and a reading light having a predetermined wavelength irradiated on the optical recording layer, for reproducing the hologram recorded on the optical recording layer, therethrough and blocks light having a shorter wavelength than the wavelength of the writing light.
