电脑的光驱对于有缺陷的光盘,读盘能力往往很弱,基本上读不出数据,甚至对一些正版盘也显示:CDR101:NOT Ready reding dive E或Abort,Retry,Ignore,Fail?即认为光驱中没有光盘或读盘失败。 光盘驱动器的信息读取原理可这样描述:半导体激光器发出0.54um～0.68um波长的光束,透过光栅与单向反射镜经瞄准透镜和接物透镜聚焦后照射到光盘的凹沟上,反射光通过接物透镜和瞄准透镜后由单向反射镜反射到光电二极管上,光驱在每个脉冲到来时读取光电二极管上的信 Computer CD-ROM For defective discs, the ability to read the disc is often weak, basically can not read the data, and even for some genuine disc also shows: CDR101: NOT Ready reding dive E or Abort, Retry, Ignore, Fail? No disc or disc failed. Optical disc drive information read principle can be described as follows: the semiconductor laser emits a 0.54um ~ 0.68um wavelength beam, through the grating and the one-way mirror through the aiming lens and the objective lens to focus on the disc after the exposure to the reflected light Through the receiving lens and aiming lens reflected by the one-way mirror to the photodiode, the optical drive reads each pulse arrives on the photodiode letter
