Method for adjusting reproduction speed of CD-ROM drive and device suitable therefor

摘要

A device and method for adjusting the reproduction speed of a CD-ROM drive according to variations of a supply voltage. The supply voltage is compared with a predetermined reference voltage. If the supply voltage is lower than the reference voltage, the rotating speed of the spindle motor is lowered to a corresponding speed. Therefore, the error correcting capability of the DSP is maintained and the reliability of a product increases.
