Information recording medium |
摘要 |
An information recording medium includes a first transparent electrode, and a carrier transport layer formed on the first transparent electrode for generating an electric current on the basis of fed carriers. A carrier generation layer formed on the carrier transport layer serves to generate carriers corresponding to a distribution of an intensity of incident information-writing light containing information, and serves to feed the generated carriers to the carrier transport layer. An electric power supply electrically connected to the first transparent electrode serves to generate an electric field corresponding to the distribution of the intensity of the incident information-writing light in cooperation with the carrier transport layer and the carrier generation layer. A photo-modulation layer formed on the carrier generation layer serves to record the information in the incident information-writing light in response to an application of the electric field generated by the electric power supply, and serves to modulate applied information-reading light in accordance with the recorded information. The photo-modulation layer is made of a complex member of high-molecule material and liquid crystal. A second transparent electrode is formed on the photo-modulation layer, and is electrically connected to the electric power supply. The carrier generation layer is made of inorganic material. The carrier generation layer may be made of organic material. In this case, a separating layer is provided between the photo-modulation layer and the carrier generation layer.
