FIELD: physics, computer engineering.
SUBSTANCE: disclosed is a device for protecting information on a digital recording medium from unauthorised access. The device has a capacitive energy storage connected to an inductor which is in form of a flat helical coil and is fixed relative the recording medium. There is a row of movable armatures in the gap between the inductor and the recording medium. Each armature is in form of an electroconductive element whose flat surface is adjacent to the inductor, and an impact element with a surface adjacent to the electroconductive element. A fixing element presses the armature to the inductor and is in form of a mesh.
EFFECT: high efficiency of protecting information on a digital recording medium from leakage, reduced size and high reliability of the device for protecting information.
