我曾有一张《中国大百科全书》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。最近使用时其中已有几本书根本无法读出来,频繁出现读读错误提示,若强行读出则会造成系统死机。因这张光盘具收藏价值,哪里舍得丢弃?拿到钟表抛光处去抛光吧,人家喊价10元,又觉得划不来。想到钟表表面抛光用的抛光粉和平绒布,自己能否照此操作呢?反正这张光盘已修复无望,权且死马当活马医吧! I had a “China Encyclopedia” CD, often scratches the surface due to frequent use, some places are still quite deep scratches. In recent use, there are already a few books that can not be read at all. Frequent read error prompts, if forced to read it will cause the system crashes. Because of this collection of CD-ROM value, where willing to discard? Get the clock polishing to go polishing it, others call out 10 yuan, but also think of it. Think of the surface of the watch with polishing powder and velveteen, can you do this? Anyway, this CD has been restored hopeless, right and dead horse living horse!
