摘要： A high-speed search method for searching a target address and for use in a disc player system having a slider for positioning a pickup for reading an information signal recorded on a disc as tracks, in a disc radius, and a tracking servo system for causing an information detecting point of the pickup to follow the track. An accelerating-and-decelerating move control mode in which the slider is accelerated and subsequently decelerated with the tracking servo loop open, and a constant speed move control mode in which the slider is moved at a constant speed by using address data obtained from a signal from the pickup are prepared, and a distance from a present position of the pickup to the target address is detected. Operations of the accelerating-and-decelerating move control mode and subsequently the constant speed move control mode are executed and the tracking servo loop is closed when the distance is equal to or greater than a predetermined value, whereas the operation of the constant speed move control mode is executed without executing the operation of the accelerating-and-decelerating move control mode and the tracking servo loop is closed when the distance is smaller than the predetermined value.

摘要： A servo loop particulary useful for a focusing or tracking servo in an optical disk. The peak-to-peak value of an error signal in the servo loop is detected while the optical pickup is being driven perpendicularly to the disk in focusing or transversely to the disk in tracking. The detected peak-to-peak value is used to adjust the gain of a variable gain amplifier included in the servo loop.
