Abstract: PURPOSE: To realize accurate code reading even if a reader is not precisely positioned by installing a non-interference area inhibiting only the existence of an interference picture having an attribute becoming an obstacle in reading a code, around the code. CONSTITUTION: In a recording medium 10 where data are recorded as a code 1 which can optically be read by manual scanning, a non-interference area (half-tone dot meshing part) 11 is formed around the code of a reading object 1. The code of the read object 1 and a code out of the read object 1' are selected according to while code an operator reads. When plural interference modes are given in accordance with an extracted feature, the non-interference areas are set in every interference mode. A non-interface picture 14 which does not interfere the extraction of the feature can freely be arranged even in the non-interference area 11. Thus, data can securely be reproduced without being interrupted by the interference of a peripheral picture even if a reader is not precisely be positioned.
