Abstract:
The present invention facilitates, in a two-dimensional symbol in which a region where additional data is recorded is provided in addition to a region where normal data is recorded, identification of colors of the regions where the respective data are recorded. Vertically and horizontally arranged first modules (2a. 2b) are provided, and by the coloration patterns of the first modules (2a, 2b), a finder pattern for detecting a symbol position, a timing pattern for specifying the center position of the first module (2a, 2b), and a first recording region where first data can be recorded are formed. In at least a partial region (8), a second module (3) is disposed in a portion that does not overlap the first module (2b) and includes an intermediate point between the first modules (2b) adjacent to each other, and a second recording region where second data can be recorded is formed by the coloration pattern of the second module (2b).
