Abstract
A recording and reproducing apparatus includes an RLL encoder that encodes an information bit string to a code bit string and a RLL decoder that decodes the code bit string to the information bit string. The RLL encoder encodes the information bit string to the code bit string of a run-length-limited code at a high encoding rate satisfying a plurality of conditions of constraint regarding a string of successive zeros. The RLL decoder decodes the code bit string encoded by the RLL encoder to the information bit string.
