Next you'll be given the option of checking the media surface — we're talking the CD media surface here, not the hard disk surface.
接下来您遇到的选项是检查介质表面-这里我们说的是CD介质表面，而不是硬盘表面。
In optical recording, a microscopic depression made on the disk surface by the recording laser beam.
在光记录技术中，由记录激光束在光盘表面上烧蚀的一个微小凹陷区。
A head crash happens when the surface of the read-write head or particles on its surface contact the magnetic disk surface.
当读写头的表面或表面上的微粒与磁盘表面接触时会发生磁头划伤。
Focal depth plays an important role in optical storage systems, and high focal depth makes the focusing servo system easy to track the disk surface.
焦深在高密度光盘存储系统中具有十分重要的作用，大焦深可以使调焦伺服系统容易跟踪盘面。
Specifically, a pressure concentration takes place. This pressure, that is, the amount of force falling on a unit of the disk surface, is very considerable.
也就是说，一个集中的压力产生了，而这种作用于椎间盘表面的压力是极大的。
The magneto-optic head flies much farther from the disk surface than a magnetic disk head, and the magnetic material is covered with a protective layer of plastic or glass;
光电磁头距离盘面的距离比磁头远，并且磁介质上覆盖有塑料或玻璃的保护层；
In optical recording, a microscopic depression made on the disk surface by the recording laser beam. Recorded information is contained in the pits and the Spaces between pits-lands.
在光记录技术中，由记录激光束在光盘表面上烧蚀的一个微小凹陷区。记录信息包含在凹区和凸区中。
Taking rigid disk surface as an example, fractal parameters are obtained by means of power spectrum and structure function, providing a proper geometric model for further contact analysis.
实验结果表明，分形维数能很好地表征表面轮廓，可为进一步的接触分析提供更合理的几何模型。
