<p>There are provided a means (101a) for evaluating a position control deviation and a means (102a) for outputting, based on a result of the evaluation, a correction signal, in which a kick brake function signal is set, to an actuator (10), thereby performing a control such that a position deviation signal does not exceed a predetermined value. Even in a case where the control deviation otherwise would increase during reproducing an optical disc having disc physical distortions, such as eccentric wobbling and shock disturbance at the occurrence of a shake or collision affecting an optical disc apparatus, it can be suppressed without losing the stability of control. Thus, stable recording/reproducing operations can be achieved at all times.</p> |
