An optical recording medium is capable of linear recording in a photon mode. An organic material changed in molecular orientation on light illumination to exhibit birefringence is used as a recording material. For example, a recording layer having, as a recording material, an organic material changed in molecular orientation caused by trans-cis rearrangement, is changed in birefringence with changes in the molecular orientation of the organic material. The recording system which utilizes the changes in the molecular orientation of the organic material has linear characteristics and gives outputs different depending on e.g., the degree or the angle of orientation, thus enabling multi-valued recording.
