ABSTRACT:
To perform a track jumping operation, fine adjustment means is forcibly driven by a speed error signal corresponding to a difference between a moving speed of an information detection point and a predetermined reference speed so that the information detecting point is controlled to jump over tracks at the predetermined reference speed and more a designated distance. Simultaneously, rough adjustment means is forcibly driven by an integrator means which integrates the speed error signal.
