有的时候,本来是出于一种好意一片爱心去做一件事情,但往往却取得了相反的效果,比如,用清洗剂清洗DVD机光头就是这样。 一台DVD机,当你用清洗剂清洗激光头后会发现它只能播放CD碟、VCD碟,但在播放DVD碟时只检索不播放。 Sometimes, it was out of kindness and love to do one thing, but often achieved the opposite effect, for example, with a cleaning agent cleaning DVD player head is like this. A DVD player, when you use a cleaning agent to clean the laser head will find it can only play CD discs, VCD discs, but when playing DVD disc only retrieve does not play.
