Zusammenfassung:	An optical pick-up actuator having a servo control system with increased stability includes a base (10), a lens holder (50) mounted on the base (10) to be tiltable about a tilting axis of the lens holder (50), at least one objective lens (1/2) being mounted on the lens holder (50), and at least one groove (52/54) being formed in the lens holder (50), and a magnet unit (80) mounted on the base (10) and extending into the at least one groove (52/54). Walls of the least one groove (52/54) facing the magnet unit (80) in a direction transverse to the tilting axis include sloping surfaces (SLP) providing a tilting margin to enable tilting control to be performed.
