In a data arrangement of a CD-ROM format, data in which DSV control data cannot be placed due to a restriction on the format is followed by control data of two bytes. Main data in which any data cannot be placed is followed by a special control data sequence of two bytes. As a result, after a data sequence of which it is unknown whether the start bit is plus or minus, the sign of the start bit of a diverging control data sequence preceded by the special control data sequence can be kept constant. Consequently, DSV values can be deviated in one direction.
