Zusammenfassung:An optical pick-up actuator (1) has a lens holder (2). The lens holder has tracking (5r) and focusing (5f) coils which substantially extend in two parallel planes at a side of the lens holder (2). A magnet system (7) is arranged separately from the lens holder and extends beyond said planes, said magnet system cooperating with the tracking and focusing coils, the coil systems being arranged for effecting tilt through cooperation with the magnet system. Preferably, a coil system is provided at each of two opposite sides of the lens holder.
