ABSTRACT:
An optical information recording medium is capable of supplying an optimum recording strategy for a high-speed recording, and for a plurality of scanning speeds, using a smaller number of parameters than conventionally required. The parameters include: Td1/T that specifies the rising time of the first pulse; Td1′/T that specifies the rising time of the first pulse, where n=3; Td2/T that specifies the rising time of the last off-pulse; Td2′/T that specifies the rising time of the last off-pulse, where n=3; Tmp/T that specifies an irradiation period for all the pulses other than the last pulse, when n is an odd number; Tmp′/T that specifies the irradiation period of the pulse, where n=3; δ/T that compensates for the irradiation period of the last pulse, where n is an odd number; and constants a and b. All or certain selections of the parameters are encoded and pre-formatted, for example, in vacant domains such as domains other than M1, S1and F1of the Additional Information-1of the optical information recording medium.
