At the time of constituting the code table 120, the code word is allocated based on a limit that a minimum run length is 3T and a maximum run length is 11T with a channel bit as T. The table is divided into seven groups 7 based on a transition state and the group can be selected in accordance with a following input data word. Thus, the run length limit is satisfied even if the code word is directly connected.
