发明名称 TRACK JUMP SIGNAL POSITIONING PICK-UP ON RECORD DISC
摘要 A device for rapidly moving an optical pick-up device in an optical reproducing apparatus to a desired position on a record disc having a plurality of record tracks with an information signal recorded therein, includes a tracking error signal generating circuit for producing a tracking error signal corresponding to deviation of the pick-up device from the center of each record track; a drive device for moving the pick-up device in a direction transverse to the record tracks; and a track jump signal forming circuit for producing a track jump signal comprised of a drive signal followed by a brake signal, in response to the tracking error signal, the drive signal having a duration corresponding to the number of tracks traversed by the pick-up device and the brake signal having a duration corresponding to the speed of movement of the optical pick-up device in traversing the tracks, and for supplying the track jump signal to the drive device to control the latter to rapidly move the optical pick-up device in a direction transverse to the record tracks to the desired position.
