ABSTRACT:
A layer jump control apparatus of an optical drive. The layer jump control apparatus has a pick up head, a preamplifier, a controller producing a focusing control signal FC, a low pass filter for receiving FC and producing a layer distance balancing signal LC, and a driving device to send a driving force to the pick up head. When the optical drive does not perform the layer jump process, the driving device receives FC. When the optical drive performs the layer jump process, the driving device receives a kicking signal and LB to determine the driving force in the kicking process; the driving device receives a braking signal and LB to determine the driving force in when the optical drive performs the braking process; and the driving device receives LB to determine the driving force in the holding process and the waiting process.
