Patent ID: 8154969

Claim:
A recording parameter setting device configured to set recording parameters for pulse sequences for forming recording marks on an information recording medium, comprising: a storage section for storing a first look-up table and a second look-up table; and recording parameter setting means for setting, as the recording parameters of the pulse sequences, recording parameters obtained from the first look-up table and the second look-up table stored in the storage section, the pulse sequences respectively forming recording marks each of which is equal to or longer than a first predetermined recording mark length but not longer than a maximum recording mark length, the pulse sequences each including: a top section including a top pulse; a last section including a cooling period; and an intermediate section including an intermediate period provided between the top section and the last section, the first look-up table storing recording parameters for the top sections as recording parameters for controlling heat of front edges of the recording marks, wherein, among the recording parameters for controlling the heat of the front edges, recording parameters for recording mark lengths each of which is equal to or longer than the first predetermined recording mark length but not longer than the maximum recording mark length have a same value, the second look-up table storing recording parameters indicative of cooling start positions for the cooling periods which cooling start positions control heat of rear edges of the recording marks, wherein, among the recording parameters indicative of the cooling start positions, (a) recording parameter(s) for recording mark length(s) each of which is equal to or longer than the first predetermined recording mark length but is shorter than a second predetermined recording mark length has/have value(s) individually set, and (b) recording parameters for recording mark lengths each of which is equal to or longer than the second predetermined recording mark length but not longer than the maximum recording mark length have a same value, and the second predetermined recording mark length being longer than the first predetermined recording mark length.
