Optical Info

光信息是从流行的系统规范剥离实用工具 - 系统信息程序已经可以显示有关光盘驱动器的信息。此实用工具的目的是检测光盘驱动器（CD/ DVD驱动器），读/写功能。看这是不是你自己的计算机前，往往是很难判断是否安装的光驱是CD - ROM，CD刻录机，CD重写，DVD - ROM，光盘重写+ DVD组合，DVD/ CD重写等。

Optical info is a spin off utility from the popular System Spec - system information program which can already display this information regarding optical drives. The purpose of this utility is to detect the optical drive's (CD / DVD drives) Read/Write capabilities. When looking at the front of a computer which is not your own it is often difficult to tell whether the optical drive installed is either a CD ROM, CD Writer, CD Rewriter, DVD ROM, CD Rewriter + DVD Combo, DVD/CD Rewriter etc.
