光驱是多媒体电脑必不可少的基本配置,在实际使用中,光驱出故障时候较多,光驱在最初出现故障时,一般是“挑盘”,以后越来越严重,直至不能读盘。这种故障通常是聚焦透镜、激光头积尘较多或激光管老华等原因引起。因此在出现不能读盘的故障后,首先可对激光头作清洁处理,包括一般除尘和清洗聚焦透镜、激光头。如果故障仍然不能排除,可能是激光电流调节电位器接触不良或者激光二极管老化所致,可尝试通过调节电位器解决。笔者处理的故障光驱中,大部分通过上述办法得以修复。
Optical drive is an indispensable multimedia computer basic configuration, in actual use, when the optical drive failure more, the initial failure of the optical drive, the general is “pick plate”, after more and more serious, can not read the disk. This failure is usually focus lens, the laser head dust more or laser tube Lao Hua and other causes. Therefore, in the event of failure can not read the disk, the first laser head for cleaning, including the general dust and cleaning lens, laser head. If the fault still can not be ruled out, it may be due to poor contact of the laser current regulating potentiometer or laser diode aging, which can be solved by adjusting the potentiometer. Most of the failed CD-ROMs that I dealt with were fixed by the above-mentioned methods.
