Abstract: An apparatus for recording information carried by an electro-magnetic radiation beam. The apparatus has a recording unit having two electrodes, a photoconductive member and a recording member of liquid crystals capable of holding electric charges, the members being arranged so as to face each other between the electrodes. An electro-magnetic radiation beam carrying information to be recorded is directed to the photoconductive member under presence of a voltage across the electrodes. An electric field corresponding to a conductivity variation of the photoconductive member according to the information is thus applied to the recording member to form a charge latent image corresponding to the information on the recording member. The recording member is then heated so that an intensity of the applied electric field exceeds a specific threshold level at which an optical characteristic of the liquid crystal begins to vary according to the charge latent image.

There is further provided a charge latent image recording method. A photo-conductive layer and a charge holding layer, each having an electrode at a surface thereof, are arranged to face each other through a gap.

At the time, an electro-magnetic wave corresponding to the charge latent image intended to be recorded is emitted to the photo-conductive layer. The impedance of the photo-conductive layer is thus varied to record the charge latent image on the charge holding layer.
