一、一台ACER CD912E光驱,不读盘,放进盘之后,“吱吱”响几下,然后自动将盘退出。 拆开后发现光头组件很新,而且没有明显的损坏迹象,便接上电源空载观察,光头能正常循迹检索,这表明光头或光驱电路部分应该没太大问题。放入一张光碟重新开机试验,同样旋转几下后便停住退盘,似有异物卡住,仔细观察见光驱内部压盘部位有一小团丝状物卡入其中,造成光盘在旋转时受阻停转,将其取出,故障消除。 事后分析,杂物有可能是厂家在装配时混入,或用户在放置光盘时随手带入的。
First, an ACER CD912E drive, do not read the disk, into the disk, the “creak” ring a few times, and then automatically exit the disk. Open the bald component found very new, and no obvious signs of damage, then connected to the power supply no-load observation, the bald can track the normal search, which shows bald or optical drive circuit part should not be too much of a problem. Put a CD-ROM re-boot test, the same rotation a few stops after the withdrawal, it seems a foreign body stuck, careful observation see the drive part of the internal pressure plate has a small group of filaments stuck in them, resulting in disc rotation Stop, remove it, eliminate the fault. After analysis, debris may be mixed with the manufacturers in the assembly, or when users put the CD-ROM readily brought into the.
