<p>A method of determining an adjust bit value for a block of write data included in a data section (71) of a recording medium, the data section including a plurality of blocks (L1 ... LF), wherein the write data is derived from user data. The method includes performing RLL code conversion on the user data to derive the write data, and involves determining the adjust bit value such that a sum of DC levels of the write data approaches zero, and determining DSV values using the user data before the RLL code conversion. The method may be employed by an adjust bit determining circuit. The determining circuit includes an encoder (34) for receiving the user data before the RLL code conversion and outputting DSV values for the user data. <IMAGE></p> |
