Abstract: An operation of a reliability value of |Pa-Pb|-Pstd of maximum-likelihood decoding results of a portion, which is equivalent to a start/end edge of a recording mark edge and has a high error generating probability in the maximum-likelihood decoding method, is performed for each combination of a prescribed mark length and a length of a space just before the mark, and for each combination of the mark length and a space just after the mark. Based on the operation results, a recording parameter is optimized, and recording is performed by having the optimized recording parameter reflected.
