光驱的变速设计是应使用者的需要而产生的,我们所说的变速光驱一般是指读盘速度可以在两个档位范围内变化的光驱。有的读者也许会问,如果档位再多一些,效果岂不更好?答案是否定的,如果档位再多的话、实际应用的意义就没有了,因为对于高倍速光驱来说、碟片的‘BUG’所引起的降速幅度会很大,分的很细的档位起不到实际作用。我们通常所见到的光驱,在处理读盘障碍时,一般会有两种解决方案,其一是仍以原来的速度读盘,直到读不出来为止;其二是降速读盘,读过后再恢复高速、我们暂且叫它无级变速。那么后者的
Optical drive design is the speed of the user’s needs arise, we say variable speed optical drive generally refers to the disk speed can be changed within the two gear range CD-ROM drive. Some readers may ask, if the gear more, the effect is not better? The answer is no, if the gear more, the practical significance of it, because for high-speed optical drive, the disc ’BUG’ caused by the deceleration rate will be great, very fine stalls play no real role. We usually see the drive, in dealing with reading obstacles, there are usually two solutions, one is still reading the disc at its original speed until it can not be read so far; the other is the speed reading disc, after reading Then resume high-speed, let’s call it CVT. Then the latter’s
