Claim:
1. A method of producing an information code by an information code producing apparatus, the method comprising: arranging, in a code area of a medium, a specification pattern region in which predetermined-shape specification patterns are arranged, the specification patterns including patterns indicating a position of the code area; arranging, in the code area, a data recording region and an error correction code recording region, wherein coded data is recorded in the data recording region by a plurality of types of cells, the cells are arranged in a predetermined code area of the medium, the cells function as a unit of information, and error correction codes are recorded in the error correction code recording region by the plurality of types of cells; arranging a free space at a position located outside the specification pattern region in the code area, the free space having a size larger in area than a single cell, the free space being excluded from error correction being performed using the error correction codes, the free space being arranged using a method which is different from a method of recording the data into the data recording region such that at least one of recording data other than the cells and displaying a design being allowed in the free space, the design being given independently of the cells arranged in the data recording region; and recording format information of the code at predetermined positions in the code area in a specified format configuration, the predetermined positions being outside of the free space.
