<p>PROBLEM TO BE SOLVED: To provide a data recording medium having encoded data which can be decoded as desired data and is recognizable when it is superposed. SOLUTION: In the data recording medium having encoded data decoded as desired data when superposed to be made recognizable, encoded data are formed to a plurality of encoded data forming parts 3 and 4 arranged to a part of a base material 2 in a positionally separated state and a separation part 7 for separating the base material is formed between these encoded data forming parts and an inspection part 20 making faithful reproduction by copying difficult is formed to the other part of the base material and, after the base material is separated, the separated base materials are mutually registered to be superposed one upon another to decode the desired data in the encoded data forming parts.</p> |
