摘要： A recording medium comprises a recording layer, a birefringent layer, and a reflecting layer. The recording layer is formed of a material whose optical rotatory power is alterable such that in one state no optical rotatory power is present and, in a second state, optical rotatory power is present. Information is recorded in the recording layer by selectively altering the state of the recording layer. The birefringent layer is formed of a material having constant birefringence without regard to the state of the recording layer. The reflecting layer reflects a light 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 is reproduced by detecting the presence of optical rotatory power of the recording layer.

摘要： A technique for improving a number of reproducible times in reproduction of information from an optical recording medium having a recording layer which reacts in a photon mode. The power of a reproducing beam is set in proximity to P.sub.rep (W) appearing in the following expression (I) or within a range of P.sub.rep (W) appearing in the following expression (II): ##EQU1## In order to improve an S-N ratio, squeezed light having suppressed photon number fluctuation is employed as a reproducing beam at need. If improvement of the number of reproducible times is in preference to improvement of the S-N ratio, such squeezed light having suppressed photon number fluctuation is employed as a reproducing beam with power which is set within a range of P.sub.rep (W) appearing in the following expression (III): ##EQU2##
