Abstract

PURPOSE:To easily perform recording and erasing of high density by forming insulator films having a charge accumulating function on a semicondutor layer, recording signals by moving a conductive recording head on this film, and erasing the recording contents by moving a conductive erase head of a specific shape at the erasing. CONSTITUTION:Insulator films 2 such as SiO2 film 2a, and Si3N4 film 2b having a charge accumulating function are formed on a semiconductor layer 1 such as P type silicon substrate, and a conductive recording head 4 applied with recording signals is relatively moved on this insulator film 2, whereby charge is injected in the films 2 and the signals are recorded. At the erasing, a conductive erase head 7 which has such a shape of the leading end face that the gap between the same and said films 2 is wider the near the relative moving direction side of the films 2, for example, a cylindrical face shape, and is applied with constant AC voltage is relatively moved on the films 2, whereby the charge in the films 2 is removed and the recording contents are erased.
