Optical recording material, optical recording medium and optical recording/reproducing apparatus

摘要

An optical recording material which includes at least one of a polymer and an oligomer, the at least one of a polymer and an oligomer comprising a photoresponsive group. The optical recording material records information through change in at least one of absorption, refractive index and shape due to irradiation of light thereto. A main chain of the at least one of a polymer and an oligomer has a side chain comprising a mesogenic unit linked thereto. The side chain comprises at least two flexible spacer groups introduced thereto, the spacer groups having lengths different from each other.
