ABSTRACT:
An example dielectric information apparatus is provided with a plurality of electrodes for recording information in a small area of a dielectric substance and an earthed electrode. The electrodes are placed such that the dielectric substance is sandwiched therebetween. The dielectric information apparatus reads out the information recorded in the small area of a dielectric thin film by applying alternating current signals to the first electrodes. The polarization direction of the small area and the direction of an applied electric field decide the dielectric constant of the small area, and the oscillation frequency of an oscillator is determined by a capacitance Cs corresponding to the dielectric constant. An oscillation signal of the oscillator is demodulated at an FM demodulator, and the information is detected from the demodulated signal at a signal detector. When recording, record signals are applied to the first electrodes, and the polarization direction is set to correspond to the record signals.
