第一：刻盘：光碟质量太差，刻录速度太快，光驱老化。

The poor quality first: disc, CD, burn too fast, light aging.

在一台运行速度极快且内存很大的机器上，您可以在刻录期间从容地处理非cpu密集型任务，但是在烧录盘期间最好别做别的事情。

On a fast machine with lots of memory, you can get away with doing low-CPU-intensive tasks during recording, but it is better to do nothing else during a burn.

cdrecord将试图以最快速度运行刻录机，因此不必指定速度，但是，应该根据经验来判断如何做。

Cdrecord will try to run the recorder at its highest speed, so it is not necessary to specify a speed, but let experience be your guide.
