    摘要： recording medium comprises a recording layer containing a material whose optical rotatory power is changed, a birefringent layer for changing a state of the polarization of a beam, and a reflecting layer for reflecting the beam transmitted through the recording layer and the birefringent layer to reintroduce the beam into the birefringent layer and the recording layer. A method of reproducing information from this recording medium applies a polarized light beam to the recording medium and detects change of the polarized state of the polarized light beam reflected from the recording medium, thereby reading the information recorded in the recording layer. According to the inventive recording medium and reproducing method, the information can be reproduced through optical rotatory power.

    摘要： Disclosed herein is a recording/reproducing method for an optical recording medium comprising a step of heating a recording layer containing a photochromic material and a polymer which are so combined with each other that a photostationary state attained upon irradiation with light of a specific wavelength is varied with temperatures, and a step of applying the light of a specific wavelength to the heated recording layer for bringing the same into a photostationary state and recording information. In order to reproduce the information, a portion of the recording layer which is in a photostationary state is selectively heated, and reproducing light is applied to reproduce recorded and unrecorded states.

    摘要： An optical memory medium having a transparent substrate, a recording layer and a reflective layer, the recording layer and the reflective layer being formed in this order on the transparent substrate. The recording layer is a diarylethene derivative dispersed in a non-polar polymeric binder. The optical memory medium with such a recording layer fully utilizes advantageous properties of the diarylethene derivative, such as good thermal stability of recorded state, excellent durability against repeated color changes between colored and colorless states, and photosensitive property to semiconductor laser light with a wavelength of 780 nm. The optical memory medium enables high-density recording and non-destructive readout.
