    • A recording method for an optical disc drive and an optical disc drive capable of preventing a light source of a laser beam or a laser driving portion from becoming uncontrollable as they are heated to high temperatures above their compensation temperatures, and thereby enabling recording to be continued in a stable manner without being interrupted or stopped until it ends. A surrounding temperature is measured by a temperature sensor serving as temperature measuring device, a set surrounding temperature is correlated with a set recording rate by using a data table stored in an internal memory of a controller serving as correlating device, and a recording rate is changed by a digital signal processing portion serving as recording control device on the basis of the surrounding temperature measuring result and the correlating result, wherein the recording rate is changed by changing a ratio of a recording operation time and a recording-stop operation time with alternately repeating a recording operation and a recording-stop operation at as low a laser beam output as playback.
    • 一种用于光盘驱动器和光盘驱动器的记录方法,其能够防止激光束或激光驱动部分的光源在被加热到高于其补偿温度的高温时变得不可控制,从而使得能够继续记录 以稳定的方式,不被中断或停止,直到它结束。 通过用作温度测量装置的温度传感器测量周围温度,通过使用存储在用作相关装置的控制器的内部存储器中的数据表将周围温度与设定的记录速率相关联,并且记录速率被改变 通过基于周围温度测量结果和相关结果用作记录控制装置的数字信号处理部分,其中通过改变记录操作时间和记录停止操作时间的比率来交替重复记录速率来改变记录速率 在重放时的激光束输出低的记录操作和记录停止操作。
