激光头是CD、VCD机读取光盘信息的重要器件,也是CD、VCD机的核心部件,其性能好坏,直接决定整机的质量。激光头是机械、电子、光学三结合的精密器件,生性脆弱,价格几乎是整机价格的一半。维修统计表明:因激光头损坏引起的故障,占整机故障的50％以上。大部分CD、VCD机,尤其是使用一两年的新机,故障的原因十有八九出在激光头上。而激光头的损坏,又多因使用、保养、维修不当引起。因此,明了激光头损坏的原因,对于延长CD、VCD机的使用寿命很有必要。本
Laser head CD, VCD machine CD-ROM read the important information, but also CD, VCD machine’s core components, its performance is good or bad, directly determines the quality of the machine. Laser head is a combination of mechanical, electronic and optical precision devices, fragile, the price is almost half the price of the machine. Maintenance statistics show that: due to laser head damage caused by failure, accounting for more than 50% of the machine failure. Most of the CD, VCD machines, especially the use of a new machine for a year or two, the reason for failure in the laser head in the first place. The laser head damage, but also due to the use, maintenance, improper maintenance caused. Therefore, understand the reason of laser head damage, for extending the CD, VCD machine life is necessary. this
