ABSTRACT:
In an information recording method, a voltage is applied to an information recording medium comprising a semiconductor layer and a layer of a ferroelectric substance overlaid on the semiconductor layer, and information is thereby recorded on the information recording medium by means of directions of polarization of the ferroelectric substance. The value of the applied voltage is set at a value such that a voltage not lower than avalanche breakdown voltage may be applied to depletion layers, which occur in the semiconductor layer. Information is thus recorded quickly.
