The stepping motor has at least a first alignment hole, and the supporting base is suitable for carrying the stepping motor and the spindle motor module. The supporting base has an opening and at least a hollow alignment boss, wherein the hollow alignment boss is disposed through the first alignment hole of the stepping motor. In addition, the external diameter of the top of the hollow alignment boss is greater than the diameter of the first alignment hole. The optical pick-up head module is connected with the stepping motor. The stepping motor is suitable for enabling the optical pick-up head module moving inside the opening. Besides, an optical disk drive applying the above traverse and a assembly method of the above stepping motor and supporting base are also proposed.
