ABSTRACT:
A recording-reproducing apparatus includes an electrode, a material that changes its intramolecular electron distribution upon the application of electromagnetic wave irradiation and an electric field provided on the electrode, and an electrically conductive probe having a pointed tip. The apparatus projects an electromagnetic wave onto the material, and applies a pulse voltage between the electrode and the conductive probe.
