INFORMATION PROTECTION METHOD AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2007 - IPC G11B5/24 

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.
