There is provided a method for controlling a stepping motor by employing a micro-step mode at deceleration or acceleration of the stepping motor, which moves an optical pickup head in a full step mode or a half step mode, to minimize lens vibration of the optical pickup head. The method includes setting an initial step of the stepping motor, applying a micro-step mode to the stepping motor at the set initial step to move the optical pickup head, and after the initial step, applying a full step mode or a half step mode to the stepping motor to accelerate the optical pickup head by a desired speed. Also, the method includes setting a late step of the stepping motor, applying a full step mode or a half step mode to the stepping motor to decelerate the optical pickup head by a desired speed, and applying a micro-step mode to the stepping motor at the set late step to move the optical pickup head.
