description | FIELD: information protection. ^ SUBSTANCE: in accordance to the invention, information protection device contains constant voltage supply, inducer, two-position key and polar capacitor, connected by the key in turns to supply and to inducer. After charging of capacitor, two-positional key is switched and polar capacitor is discharged onto inducer. Current i1 occurring during that induces current i2 in electro-conductive disk of anchor. In case of possible information loss risk due to induced currents in electro-conductive disk of anchor during appearance of magnetic field impulse and return element, reciprocal movement of anchor is performed, which pushes a striker with sharp end facing information carrier until it is mechanically damaged. After subsiding of currents i1 and i2 anchor returns to original position under effect of return element. ^ EFFECT: increased efficiency of information protection method and device for its realization. ^ 2 cl, 3 dwg |
