Patent ID: 8169869

Claim:
A recording parameter setting device configured to set recording parameters for pulse sequences for forming recording marks on an information recording medium in accordance with recording information, comprising: a storage section or means for storing a first look-up table and a second look-up table; and recording parameter setting means for setting the recording parameters as the recording parameters of the sequences by obtaining, from the first look-up table and the second look-up table, recording parameters corresponding to the recording information, the pulse sequences including: pulse sequences respectively forming recording marks of a first predetermined recording mark length through a maximum recording mark length, the pulse sequences each including: a top section including a top pulse; a last section including a last pulse and a cooling period; and an intermediate section including an intermediate period provided between the top section and the last section; and pulse sequences respectively forming recording marks of a recording mark length shorter than the first predetermined recording mark length through a minimum recording mark length, the pulse sequences each including: a top section including a top pulse; and a last section including no last pulse and a cooling period, the first look-up table storing recording parameters for the top sections which recording parameters control heat of front edges of the recording marks, wherein the recording parameters for the top sections are classified in accordance with at least recording mark lengths out of the recording information, and, among the recording parameters for the top sections, recording parameters for the top sections of the first predetermined recording mark length through the maximum recording mark length are classified into a same group, the second look-up table storing recording parameters for the last sections which recording parameters control heat of rear edges of the recording marks, wherein the recording parameters for the last sections are classified in accordance with at least recording mark lengths out of the recording information, and, among the recording parameters for the last sections, recording parameters for last sections of a second predetermined recording mark length through the maximum recording mark length are classified into a same group, and the second predetermined recording mark length is longer than the first predetermined recording mark length.
