Abstract
In a modulation processing unit, m bits of input data are converted to an n bit fixed length code. In an RML conversion unit, a restriction code which limits a minimum run d in a channel bit sequence after converting the fixed length code from repeatedly occurring a predetermined number of times, is converted to a data sequence. A clock is stably reproduced.
