Title: Track jump controller for optical information recording and reproducing device
Inventor: NAKANO JUNICHI
IPC: G11B7/085
Filed: 1990-04-19
Abstract: PURPOSE:To stably lead a spot to a target track by turning on the tracking servo to lead the spot to the target track even at the time when the spot is difficult to reach the track and decelerating it by a deceleration pulse of additional output at the time of overrunning the target track. CONSTITUTION:When a start signal START is inputted to a pulse generating circuit 17, a counter 21 of the circuit 17 outputs an acceleration indicating pulse KP, and an FF 25 of a control signal generating circuit 16 sets an output POS to the low level, and a switch 13 is turned off to turn off the tracking servo. The light spot is moved to adjacent tracks by the pulse KP, and it is positively increased as a tracking error signal TES. After a prescribed time, a deceleration pulse BP is outputted from the circuit 17 and is outputted as a jump signal JP through a differential amplifier 23. When the light spot overruns the target track, the signal JP is additionally outputted through the amplifier 23. Thus, the light spot is quickly led into the target track so as to lead back to the target track.
