OPTICAL RECORDING METHOD

摘要

When recording mark-length-modulated information on a recording medium, m record pulses alphaiT and m off pulses betaiT are used to form the record mark length nT of one record mark, the leading record pulse alpha1T will rise a time dTtop deviated from the leading position of a record mark, all record marks involving m of at least 2 satisfy 2.5 <= n/m, when a plurality of different record mark lengths are respectively formed by the same pulse division number m, record mark lengths having different lengths are respectively formed by varying alpha1 and/or alpham, and when alpha1 is varied, dTtop and/or beta1 are varied, and when alpham is varied, betam-1 and/or betam are varied.
