    摘要： An optical information recording medium having a laminated structure of a charge image forming layer (CFL) and a photomodulation layer (PML). An electrode (Et) may be formed on the outer surface of the photo-­modulation layer. A dielectric mirror (DML) may be disposed between the charge image forming layer and the photomodulation layer. A charge motion suppressing layer (ESL) may be disposed on the outer surface of the charge image forming layer. The charge image forming layer may be constructed of a dielectric layer with photoconductive fine particles (PCG) distributed therein, and a dielectric thin film formed on the dielectric layer. A charge motion suppressing layer (ESL) may be disposed on the outer surface of the charge image forming layer. An electrode may be formed on the outer surface of the photomodulation layer. A dielectric mirror may be formed between the charge image forming layer and the photo-modulation layer. An electrode may be formed on the outer surface of the photo-modulation layer. There is further provided an optical information recording medium having a laminated structure of at least a dielectric layer and a liquid crystal layer (LC) using high polymer as a binder. An electrode may be formed on the outer surface of the liquid crystal layer. The dielectric layer may be formed by a charge image forming layer (CFL). The dielectric layer may be formed by a dielectric layer (IL) and a charge motion suppressing layer (ESL). There is further provided an optical information recording medium having a laminated structure of at least a photoconductive layer (PCL) and a liquid crystal layer (LC) using high polymer as a binder. Also provided is a recording/reproducing system for optical information which uses such recording mediums.

    摘要： There is disclosed a recording/reproducing system comprising an optical system for directing along a path of an electromagnetic radio ray from an object toward a recording medium, and a recording head disposed in the path for generating a charge latent image onto the medium. The feature of the system resides in that the recording head (system) forms the detection region which is not entirely subject to the influence of the electromagnetic radio ray and which is provided in a portion of the charge recording region of the medium, and in that a reproducing system discriminates the polarity of charges or the recording mode of the charge latent image recorded onto the medium by detecting the charges in the detection region.

    摘要： Method and apparatus for recording information on a recording media (415) comprising a polymer material including electrooptically active molecules (415). The electrooptical properties of the material are modified at selected locations (416 and 417) of the media in correspondance of the information to be recorded. The recorded information can be read by detecting variations in the electrooptical properties of the polymer material across the media (411).
