Abstract
A holographic recording medium including a recording layer on a substrate, which records data information in a light interference pattern. 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.
Claims3
A holographic recording medium comprising:
- a recording layer on a substrate, which records data information in a light interference pattern,
- wherein at least one of information on a thermal expansion characteristic of a recording material contained in the recording layer and information on temperature dependency of the refractive index of the recording material are recorded within the holographic recording medium in advance.
Dependencies are inferred from the claim text.
