Abstract
A voltage of an intensity corresponding to information to be recorded is applied to a recording medium which comprises a film containing a charge generating material. The film is sandwiched between two electrodes. Electric charges are accumulated in the recording medium upon application of the voltage so that information is recorded. When light is irradiated to the recording medium, the stored charges are converted into photo-current. The recorded information is read out by detecting the photo-current. When the electrodes are short-circuited, the recorded information is erased.
