METHOD AND APPARATUS FOR DELETING RECORDED INFORMATION

摘要

FIELD: information technology. ^ SUBSTANCE: microcircuit is placed on a flat heat reflector made from nonmagnetic metal between annular throttles of a field-converting system such that the plane of the substrate of the microcircuit is parallel to the plane of the annular throttles of the field-converting system. The microcircuit is exposed to pulses of a sinusoidal electromagnetic field at frequency higher than 200 kHz, duration of not less than 1.5 ms and radiation intensity of not less than 167 kW per pulse. Also, the amplitude of each pulse of the sinusoidal electromagnetic field falls with time. ^ EFFECT: high reliability of deleting information, reduced power consumption and simple design of the apparatus for deleting information. ^ 2 cl, 3 dwg
