Abstract:
A holographic recording medium including a recording layer on a substrate, which records data information in a light interference pattern is provided. In the holographic recording medium, information on a thermal expansion characteristic of a recording material contained in the recording layer and/or information on temperature dependency of the refractive index of the recording material are recorded within the holographic recording medium in advance.
