A method for moving a sledge disposed thereon an optical pickup head of an optical disc drive is provided for controlling the motion of the sledge relative to an optical disc loaded. The optical disc drive further includes a sledge motor. At first, the sledge motor drives the sledge to move toward the center of the optical disc. At the same time, the tracks crossed by the optical pickup head are detected and counted according to a tracking error signal generated by the optical pickup head. When the count or an increment in the count within a specific period is not larger than a predetermined value or the tracking error signal is undetectable, the optical disc drive immediately stops the sledge motor from driving the sledge. The monitoring mechanism can avoid undesired impact and noises of the sledge.
