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. Therefore, the information is recorded in the recording member as the optical characteristic variation.
