Abstract
A dielectric reproducing device and a dielectric recording and reproducing device that can improve the reproduction speed. A detection means is provided so as to be able to detect a polarization state of each bit 1a corresponding to the data recorded in a data recording layer by relatively scanning the data recording layer made of a dielectric material. A heating means is provided so as to be able to heat the bit to be detected to a predetermined temperature while the detection means detects the polarization state. A reproducing means is provided so as to be able to reproduce the data based on the polarization state of each bit detected by the detection means.
