초록

본 논문에서는 Blu-ray 디스크의 기록을 위한 Laser Diode의 온도특성을 고려한 기록품질의 개선방법에 대해 연구했다. 주변 온도변화에 따라 Blu-ray Laser Diode는 전류-전압 관계로부터 미분저항이 변화하게 되는데 이러한 미분저항이 저온에서 기록품질에 미치는 영향에 대해 분석하고 개선하는 방법을 제안한다.

In this paper, we research the method for write quality improvement by temperature characteristic of Laser diode for optical recording. Differential Resistance of Blu-ray laser diode is changed by temperature. We analyze the effect of the change of the differential resistance in low temperature and propose the method for the write quality improvement.
