An information storage device includes a cathodoconductive medium and pairs of electrodes in contact with the medium. Data storage areas are located within regions between the electrode pairs. A read operation on data storage areas between a pair of electrodes may be performed by creating an electric field between the electrodes, scanning an electron beam across the storage areas, and monitoring a cathodocurrent created by the carriers. Changes in magnitude of the cathodocurrent indicates the states of the storage areas. The energy beam may be supplied by an electron emitter or a near-field optical source.
