Abstract:
A disc drive apparatus (1) for optical discs (2) comprises: a frame (3); a sledge (10) displaceably mounted with respect to said frame (3); a lens actuator (43, 21) displaceably mounted with respect to said sledge (10); and a control unit (90) for generating a control signal (SCL) for the lens actuator (43, 21). The control unit (90) is designed, during a jump operation, to generate said control signal (SCL) for the lens actuator (43, 21) on the basis of an actuator deviation signal (SAS) representing a difference between actuator position (XA) and sledge position (XS).
