Abstract: An optical drive comprises a radio frequency processing unit, a memory, a digital signal processing unit, and a driving processing unit. The radio frequency processing unit enlarges a signal generated with an optical pickup and produces a tracking error signal and a servo signal. The memory saves a plurality of sled processing programs. The digital signal processing unit has a tracking processing module and a sled selecting module. The tracking processing module processes the tracking error signal and produces a tracking output signal. The sled selecting module selects one of the sled processing programs according to the servo signal for processing the tracking output signal and producing a feed output signal. The driving processing unit drives a coil motor and a sled motor respectively according to the tracking output signal and the feed output signal.
