A code encoding device for outputting character, audio, and moving picture data converted to color marks by referring to a code conversion table ( 104, 204 ) and a code decoding device for outputting color marks converted to character, audio, and moving picture data by referring to a code conversion table ( 112, 212 ). High density recording is made possible through the medium of color marks. At the time of encoding and decoding of data, one unit of data is linked with one color among the plurality of colors to enable high density recording compared with conventional bar codes and two-dimensional codes.
