<P>PROBLEM TO BE SOLVED: To provide an information recording method by which recording strategy can be prescribed with less parameters. <P>SOLUTION: Width of sum of a high pulse and a low pulse of a multi-pulse when mark length corresponding to time length nT is recorded is shorter than the time length nT, when even number (n) is used as reference and (n) being the reference is increased by 2, the number of the high pulse and the low pulse are increased respectively by one to record mark length corresponding to it, when (n) is increased by 1, the number of the high pulse and the low pulse for recording mark length corresponding to it are same respectively as the number of the high pulse and the low pulse for recording mark length corresponding to (n), also, width of at least one low pulse existing in the high pulse is made longer than width of one low pulse existing in the high pulse for recording mark length corresponding to (n). <P>COPYRIGHT: (C)2007,JPO&INPIT |
