摘要：
The present invention provides a filter for optical recording medium capable of preventing diffuse reflection of an information beam and a reference beam from a reflective layer in the optical recording medium and preventing occurrence of noise without causing shift in selective reflection wavelength, and distortion in a reproduced image even when an angle of incidence is changed, and an optical recording medium capable of recording a high density image by using the filter. Specifically, the present invention relates to the optical recording medium containing a first substrate, a recording layer which records information by utilizing holography, an optical compensation layer, a filter layer, and a second substrate, in this order, and the filter layer is a cholesteric liquid crystal layer.
