ABSTRACT:
An apparatus and method of controlling tracking in a disc drive using a tracking actuator, a feed motor, and an objective lens, including monitoring whether the tracking actuator deviates from a dynamic range based on a signal controlling the feed motor when tracking is performed; and returning the objective lens connected to the tracking actuator to a neutral point when it is determined that the tracking actuator deviates from the dynamic range.
