Abstract: PROBLEM TO BE SOLVED: To promote high density recording by keeping restriction on a set minimum run (d) and maximum run (k), inserting a digital sum value(DSV) control code by a number of bits having redundancy as less as possible and performing DSV control. SOLUTION: In encoding processing for inserting a DSV control code into a (d, k) run length limited RLL code string for performing DSV control, the (m) bit DSV control code of a bit pattern, for keeping the (d, k) limit and performing DSV control, is substituted for the bit pattern of a bit string to be substituted having (a) bits forming the original (d, k) RLL code string and the substantial redundancy of DSV control is made to be (m-a) bits. At the time of decoding processing for acquiring the (d, k) RLL code of released DSV control, the substituted bit selected by the corresponding information of the (m) bit DSV control code bit pattern to the (a) bit substituted string bit pattern is inserted into the (d, k) RLL code string and the control code is removed.
