FIELD: medical engineering. SUBSTANCE: method involves carrying out engineering techniques of general use in the field of engineering practice and TV engineering in particular. Protection wave energy information is recorded for instance on magnetic carrier to be multiply reusable and rerecordable. In recording and reproducing the field, all its protection properties retain their original parameters. Being rerecorded, the information signal weakens. EFFECT: enhanced effectiveness in delivering and receiving information. 9 cl
