<P>PROBLEM TO BE SOLVED: To provide a two-dimensional code capable of recording a second two-dimensional code without reducing the amount of information of the original two-dimensional code. <P>SOLUTION: According to a QR code 10 related to this embodiment, since a micro QR code 16 is recorded instead of a bright module or dark module of the same color arranged in a square n×n module 11' being an aggregate of unit modules 11 or unit cells constituting a functional pattern, the micro QR code 16 can be recorded without reducing data patterns DP and regions thereof. Thereby, the micro RQ code 16 can be recorded without reducing the amount of information of the original QR code 10. <P>COPYRIGHT: (C)2009,JPO&INPIT |
