FIELD: data medium engineering. ^ SUBSTANCE: proposed data medium has at least two antennas, corresponding to different transmission ranges. In this case the data medium may be fabricated such a way that it is ensured possibility of operation with devices for record/read, functioning in accordance with different standards. At least two from the antennas produce a single unit. Owing to this union the developed data medium may be fabricated with high efficiency. ^ EFFECT: technical result of the invention is increased economic efficiency of data medium fabrication. ^ 3 cl, 4 dwg |
