Filed: 1990-09-28
Abstract: PURPOSE:To prevent the generation of yawing by negating the change of the load applied to the bearing surface of a lower stage by a load compensating machine. CONSTITUTION:The center of gravity of an upper stage table 19 is moved in the direction shown by an arrow 22 by the driving of an upper stage table driving motor 20 and, in this state, the force applied to a slide bearing 4 is increased and the force applied to a slide bearing 4' is reduced.

Filed: 1988-10-13
Abstract: PURPOSE:To perform the track jump actions at high speed by with high stability in a simple constitution by setting the frequency of the gain intersecting point of a tracking servo system and the time of the track jump pulse at the optimum value respectively. CONSTITUTION:When a switch 5 is kept at the (a) side, the frequency of the gain intersecting point of a tracking servo system is set at f1 by an equalizer 3. When the switch 5 is set at the (b) side, the frequency of the frequency of the loop gain intersecting point of the tracking servo system is set at f2. A track jump pulse is applied to a terminal 9 at a prescribed time point t2 and the jump of a light beam is started to a contiguous track on an optical disk. Then a negative polarity pulse is supplied between time points t3 and t4 so that the light beam is moved over the continuous tracks. Thus the response time of the tracking servo system is decided by the frequency of the gain intersecting point. Then only a tracking drive element 8 has the displacement and the light beam is moved by an extent equal to one track on the optical disk. Thus the stable track jump actions are attained.
