PURPOSE:To write information with the same irradiation light quantity without performing trial write on an optical disk used even once in every case in an optical disk device. CONSTITUTION:For example, the trial write is performed when the optical disk 1 is used for the first time, and a light quantity value for the optimum write on the optical disk 1 can be obtained. An obtained optimum light quantity value is registered on an EEPROM 70 with the control data of the optical disk 1. Hereinafter, the write of the information on the optical disk 1 is performed by controlling a laser control circuit 51 according to the optimum light quantity value stored in the EEPROM 70, and generating laser power with power in accordance with the optimum light quantity value from a laser diode 9. |
