Abstract

PURPOSE:To enable high density recording by providing plural probe electrodes, a recording medium having an electric memory effect, a voltage impressing means for impressing a voltage which is not more than a threshold voltage for generating the electric memory effect from the electrodes to the recording medium and a means for reading a variation of an electric current amt. flowing in the recording medium. CONSTITUTION:The titled device possesses the plural probe electrodes 102a, 102b and 102c, the recording medium 1 with the electric memory effect, the voltage impressing means (pulse electric power source) 108 for impressing the voltage which is not more than the threshold voltage for generating the electric memory effect from the probe electrodes 102a, 102b and 102c to the recording medium 1 and the reading means for reading the variation of the electric current amt. flowing in the recording medium 1. Then, the voltage not more than the threshold voltage for generating the electric memory effect from the probe electrodes to the recording medium with the electric memory effect and also the reproducing device; is impressed, so as to read the variation of the electric current amt. flowing in the recording medium. By this method, the far higher density recording than the optical recording if compared is feasible.
