Abstract The control method of automatic balance system of optical disk of optical disk drive is characterized by that it utilizes an additional force to make quality of balance be in the perturbed state in the course of main shaft motor acceleration and before its rotating speed is not higher than playback critical velocity to reduce friction resistance and make the quality of balance smoothly move toward inverse position of unbalanced vector of optical disk, after the rotating seed of main shaft motor is higher than the critical velocity, remove the perturbation force and continuously accelerate the motor to maximum rotating speed.
