ABSTRACT:
An information recording medium comprises a semiconductor layer and a layer of a ferroelectric substance overlaid on the semiconductor layer, information being recorded by means of directions of polarization of the ferroelectric substance. The ferroelectric substance is an organic ferroelectric substance, such that recorded information may not be lost during its reproduction and a sufficiently high level of a reproduced signal may be obtained.
