FIELD: medical engineering. SUBSTANCE: device has to units each of which has active layer manufactured from para- or ferromagnetic material, the active layers are connected to each other in direct way or via an interlayer manufactured from electromagnetic radiation- transparent material with their contact surfaces. The active layers of the units are preliminarily polarized with the same external electromagnetic field waves from biologically significant information carriers with spectral radiation analog elements being concurrently recorded on active layer, before being connected to each other. EFFECT: enhanced effectiveness of recorded information protection. 6 cl, 5 dwg
