ABSTRACT:
An information recording medium has a semiconductor layer and a ferroelectric layer formed thereon. Information is recorded on the recording medium by locally applying an electric voltage modulated according to the information to the recording medium and then removing it therefrom so that the ferroelectric layer is polarized by an electric charge produced by application of the electric voltage. The electric charge is caused to stay on the surface of the ferroelectric layer for at least 0.1 msec after removal of the electric voltage.
