Method for controlling track jumps of optical pickup

Disclosed is a method for controlling track jumps of an optical pickup. More particularly, the present invention relates to a method for controlling the track jumps of an optical pickup incorporated in an optical disc apparatus by controlling the optical pickup in fine-tuned fashion such that the optical pickup is moved rapidly and accurately to a target track without suffering from any disturbances such as scars on the disc. To control track jumps of the optical pickup for high-speed access to a target track freeing from any effects of disturbances, time intervals of a TZC (tracking zero cross) signal are measured continuously for comparison between a target time and a measured time required for a track jump by the optical pickup; the difference in time is computed as an error; and a control signal with a voltage or a pulse width reflecting the magnitude of the error is outputted to an actuator of the optical pickup. In controlling the driving speed of the actuator, the comparison between the target and measured times takes into account not only a time difference regarding the preceding track jump but also time differences with respect to a number of the previous track jumps. These time differences are illustratively averaged to yield a mean value, which is used as a basis for generating a control signal.
