摘要： 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.

摘要： A magneto-optical recording medium, which is for recording and reproduction of information by focusing of light of a wavelength/numerical aperture of about 1000 nm or less, has a light transmitting first dielectric layer having a first surface to which light strikes. A magneto-optical recording layer is formed on a back surface of the first surface of the first dielectric layer. A light transmitting metal layer is formed on the magneto-optical recording layer to a predetermined thickness required for dispersion of heat (about 10 nm or more) from the magneto-optical recording layer and having a larger heat conductivity than the magneto-optical recording layer. A light transmitting second dielectric layer is formed on the light transmitting metal layer. A metal reflective layer is formed on the second dielectric layer and reflects the light.
