A control system and method for controlling a sled of an optical storage device by using a stepping motor. The optical storage device includes a pick-up head having a lens and a sled. The control system includes a tracking actuator's controller used to receive a tracking signal TE for generating a tracking control signal TRO to control positions of the lens; a numerical controller connected with the tracking actuator's controller used to receive the tracking control signal TRO for generating a numerical control signal; a frequency converter connected with the numerical controller used to receive the numerical control signal for generating a pulse flag signal and a direction flag signal; and a ring generator connected with the frequency converter used to receive the pulse and direction flag signal for producing a sled control signal to drive the stepping motor for controlling the sled.
