Abstract

PROBLEM TO BE SOLVED: To exactly judge the remaining life of an optical information recording and reproducing device. SOLUTION: When there is an instruction for irradiation with a light laser by a pickup from a host computer (Y of a step S1), a drive controller starts measuring the output power of the light laser and the time for irradiation with the light laser (a step S2). To stop the irradiation with the light laser, the drive controller emits the instruction to end the irradiation with the light laser and therefore the drive controller ends the measurement of the time for the irradiation with the light laser and the output power of the light laser.
