Abstract
A method is provided for determining whether a rotating disk in an optical disk reading device is unbalanced. According to the method, the disk is first rotated at a preset rotational speed, and a lens is then located to a first position. Then, as the lens is moved towards a second position at a predetermined speed, a time duration during which a preliminary signal is generated is determined. The disk is determined to be unbalanced if the time duration exceeds a preset value.
