A method of on-line adjusting a sled motor control signal (FMO) is disclosed. First, a predetermined FMO is assigned to move a sled for seeking, and a photo signal is monitored. The number of waveforms appearing in the photo signal and a distance from an optical pickup to a target track are calculated under this predetermined FMO. Then, the optical pickup is moved to the target track such that the optical pickup after seeking is located at a center position of a movable range. If the number of waveforms appearing in the photo signal is not equal to a predetermined number, the duration of the FMO is adjusted according to the difference therebetween.
