ABSTRACT:
An information recording medium comprises a silicon substrate, a silicon dioxide film formed on one principal surface of the semiconductor substrate and a silicon nitride film formed on the silicon dioxide film. A recording electrode stylus is moved relative to and along the surface of the silicon nitride film while applying a recording signal voltage between the stylus and substrate, thus causing charges corresponding to the recording signal voltage to be passed through the silicon dioxide film by the tunnel effect and stored in the silicon nitride film.
