摘要

A recording parameter setting device configured to set a recording parameter for forming a recording mark on an information recording medium in accordance with recording information,
wherein the recording parameters include:
(a) recording parameters used for controlling heat of a front edge of the recording mark (dTtop), classified in accordance with at least recording mark lengths out of the recording information, and classified into the same group if the recording mark length is equal to or longer than a predetermined recording mark length (eg. 4T or longer); and
(b) recording parameters used for controlling heat of a rear edge of the recording mark (dTlp), classified in accordance with at least the recording mark lengths out of the recording information, and classified into more detailed groups than the recording parameters used for controlling the heat of the front edge if the recording mark length is equal to or longer than the predetermined recording mark length.
