我有一张学习光盘,因经常使用造成表面多处划伤,有的地方划痕还相当深。后来使用时有的内容根本无法读出来,频繁出现读盘错误提示,若强行读出则会造成系统死机。给我的学习带来了一定的麻烦,而又舍不得扔掉它。于是,我采用钟表表面抛光使用抛光粉和平绒布的方法,自己动手,试修复这张光盘。 I have a study CD, because of the frequent use of the surface caused by multiple scratches, scratches in some places is still quite deep. Later use of some content simply can not read out, read the disk error frequently prompted, if forced to read will cause the system crashes. Brought my study a certain amount of trouble, but reluctant to throw it away. So, I use the watch surface polishing method using polishing powder and velveteen, do it yourself, try to repair this CD.
