ABSTRACT:
An apparatus for detecting an oscillation of a servo controller of an optical disk is provided. An oscillation detector, electrically coupled to the servo controller of the optical disk, is provided and is configured to receive an error signal associated with the servo controller. The oscillation detector is further configured to compare an amplitude, a width and a period of the error signal with a reference amplitude, a reference width and reference period to determine if an oscillation is present in the error signal. Related methods and computer program products are provided.
