Dielectric reproducing device and dielectric recording and reproducing device

A dielectric reproducing device for reproducing data recorded on a data recording layer made of a dielectric material,

• the data recording layer being capable of recording data based on a polarization state of each bit formed on the dielectric material, the dielectric reproducing device comprising:
• a detection means provided to be able to detect a nonlinear dielectric constant due to the polarization state of each bit corresponding to the data by relatively scanning the data recording layer;
• a heating means provided to be able to heat the bit to be detected to a predetermined temperature while the detection means detects the nonlinear dielectric constant due to the polarization state;
• and
• a reproducing means provided to be able to reproduce the data based on the nonlinear dielectric constant due to the polarization state of each bit detected by the detection means.
