Способ защиты информации на накопителе на жестких магнитных дисках и устройство для его осуществления

Abstract

Method to protect information on storage of a hard magnetic drive (HMDS) includes arrival of an information leakage risk signal to a controller, afterwards, capacitance storage charging starts from a battery. From the battery the DC voltage is supplied to a converter, at the output of which there is a series of high-frequency pulses generated. Using a transformer and a rectifier, the voltage is sent to the capacitance storage. As voltage of discharger actuation is achieved, the capacitance storage discharges to an inductor. The current pulse in the inductor excites magnetic field, which in electroconductive elements of HMDS induces currents and causes mechanical forces that damage HMDS.
