Optical recording material, optical recording medium, and optical recording / reproducing apparatus |
| abstract |
PROBLEM TO BE SOLVED: To maintain a high recording sensitivity, dynamic range and high diffraction efficiency by controlling the length of a main chain spacer group, and to increase the film thickness, and a photosensitive layer without impairing recording characteristics It is to provide an optical recording medium capable of large-capacity recording and an optical recording / reproducing apparatus capable of recording and reproducing large-capacity data. An optical recording material comprising a polymer or an oligomer containing a site of a photoresponsive group, and recording information using absorption change, refractive index change, or shape change accompanying light irradiation, the polymer or An optical recording material, wherein a side chain containing a mesogenic group is linked to the main chain of the oligomer, and two or more spacer groups having different flexibility and length are introduced into the main chain. is there.
