1. CD-ROM drive servo-drive system is characterized in that including:

  • One read/write head is used for detecting the signal that reflected by a CD to produce a plurality of detection signals;

    One gain stage is coupled to described read/write head, is used for determining a yield value according to an output level of this read/write head, and adjusts the signal intensity of this detection signal according to this yield value;

    AndOne servosignal generator is coupled to described gain stage, is used for producing a servosignal according to this adjusted detection signal that this gain stage is exported.
