PROBLEM TO BE SOLVED: To reduce the occurrence of the reading error due to the deformation of a display area. SOLUTION: When the data recording of digital recording paper in which the digital data composed of 2<n> binary data is recorded in a square display area in binary direction is performed, the center of the recording location of the binary data is recorded at the intersection point of an X-axis internal line 2A and a Y-axis internal line 1A. When the reading of the data recording of digital recording paper is performed, the intersection point of the X-axis internal line 2A and the Y-axis internal line 1A is calculated as a mark area base point and the binary data of the two-dimensional arrangement is read and the reading of the recorded two-dimensional data is performed by the detection of the existence of the binary data within the range of the mark area. |
