摘要： A dielectric recording / reproducing apparatus (3) is provided with: a probe (11) for applying an electric field to a dielectric material (17); a return electrode (12) for returning the high frequency electric field for data reproduction; an inductor (L) placed between the probe and the return electrode; an oscillator (13) which oscillates at a resonance frequency determined according to the inductor and a capacitance formed in the dielectric material just under the probe; a switch (30) for switching circuit connections depending on whether data recording is performed and data reproducing is performed; a recording signal input device (31) for converting data to be recorded to generate a recording signal; a direct current voltage generation device (32) for generating a direct current bias voltage to be applied to the dielectric material; a frequency-amplitude demodulator (33) for demodulating an oscillation signal of the oscillator having the frequency that is changed depending on the capacitance owned by the dielectric material just under the probe; and a signal detector (34) for detecting data from the demodulated signal.
