    • An optical disk device is provided in which stable operation is realized even when an offset amount of a signal to be used for servo control changes due to environmental variations. The optical disk device generates a signal for servo control based on signals corresponding to a reflected light of a laser light irradiated to an optical disk, and detects an offset superimposed on a signal for the servo control. The optical disk device compensates the amount of the adjusted offset which has been set up so as to reduce the offset amount in initial setting for light detection corresponding to an optical disk loaded, according to the amount of change of the offset amount detected, adjusts the signal to be used for the servo control based on the amount of the offset control after the compensation, and performs the servo control based on the adjusted signal.
    • 提供一种光盘装置,其中即使当由于环境变化而要用于伺服控制的信号的偏移量变化时,也能够实现稳定的操作。 光盘装置基于与照射到光盘的激光的反射光对应的信号,生成用于伺服控制的信号,并且检测叠加在用于伺服控制的信号上的偏移。 光盘装置根据检测到的偏移量的变化量,补偿已设定的经调整的偏移量,以减少与装入的光盘对应的光检测的初始设定中的偏移量, 信号用于基于补偿后的偏移控制量的伺服控制,并且基于调整后的信号执行伺服控制。

    • It is desired that the overshooting and undershooting of optical pulse waveforms of optical pickups included in optical disk devices be reduced to improve the quality of recording. Among pulses to be recorded, the trailing edge of each last pulse and the leading edge of the subsequent erase top pulse are made to almost coincide with each other. Ratio a/b, where a is the difference between erase top pulse power level Pet and erasing power level Pe and b is the difference between recording power level Pw and the erasing power level Pe, is adjusted to realize an optical pulse waveform with reduced overshooting and undershooting for each of different recording media. Erase top pulse duration Tert is switched according to different recording speeds for different recording media.
