Claims
- 1. An information recording and reproducing method, wherein an information recording medium is placed face-to-face to a photosensitive member having a photoconductive layer on an electrode layer with an air gap therebetween, said information recording medium comprising a resin member with liquid crystal phase dispersed and fixed on an electrode layer, and there are provided an information recording layer selected in such manner that refractive index of said resin member approximately consistent with refractive index when liquid crystal substance is oriented by electric field and a charge retaining layer formed on said information recording layer, whereby pattern exposure is performed by irradiating information light from direction of the photosensitive member or the information recording medium while voltage is applied between the two electrodes, information is recorded to liquid crystal of the information recording layer according to intensity of the pattern exposure, the information is recorded as visible information, the visible information is stored as said information recording medium, and said visible information is reproduced from the information recording medium at any desired time.
- 2. A method of recording and reproducing information as claimed in claim 1, wherein said recorded visible information is reproduced by transmitted or reflected light.
- 3. A method of recording and reproducing information according to claim 1, wherein said exposure step establishes an electrostatic charge distribution providing said influence upon the select crystals of said information recording layer in accordance with the patterned illumination.
- 4. A method of recording and reproducing information according to claim 1, further comprising heating said information recording medium by passing a current through its associated electrode layer during the course of recording information thereon.
- 5. A method of recording and reproducing information according to claim 1, further comprising receiving the information via a camera or laser.
- 6. A method of recording and reproducing information according to claim 1, wherein the liquid crystal content of said information recording medium is 10 to 80 percent by weight.
- 7. A method according to claim 1, wherein said recording medium further comprises an electrically insulating charge carrier layer on its surface.
- 8. A method according to claim 1, wherein said recording medium further comprises a charge block layer adjacent the information recording layer.
- 9. An information recording and reproducing method, wherein an information recording medium is placed face-to-face to a photosensitive member having a photoconductive layer on an electrode layer with an air gap therebetween, said information recording medium comprising a resin member with liquid crystal phase dispersed and fixed on an electrode layer, and there are provided an information recording layer selected in such manner that refractive index of said crystal substance is oriented by electric field and a charge retaining layer formed on said information recording layer, whereby information is recorded by information exposure from direction of the photosensitive member or the information recording medium while voltage is applied between the two electrodes, the information is recorded as visible information, said visible information is stored as said information recording medium, and said visible information is reproduced at any desired time, whereby the information recording medium is heated to higher than room temperature and lower than isotropic phase transition temperature of the liquid crystal substance prior to the information recording on the information recording medium.
