<p>An information storage device (100) includes a cathodo-conductive medium (104) and pairs of electrodes (106 and 108) in contact with the medium (104). Data storage areas are located within regions between the electrode pairs (106 and 108). A read operation on data storage areas between a pair of electrodes (106 and 108) may be performed by creating an electric field between the electrodes (106 and 108), scanning an electron beam (120) across the storage areas, and monitoring a cathodo-current created by the carriers. Changes in magnitude of the cathodo-current indicate the states of the storage areas. The energy beam may be supplied by an electron emitter (118) or a near-field optical source.</p> |
