摘要： 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.

摘要： An optical pickup actuator for low building height includes a suspended lensholder (101) with a lenssystem (102), focusing (106a, 106b, 106c 106d) and tracking coils (109) and magnets (107a, 107b, 107c) for cooperation with the focusing and tracking coils. The focusing and tracking coils may be arranged for tilting the lensholder in the actuator. The lowest entrance position for a radiation beam to enter a beam entrance (113) at a side of the actuator is not determined by the height and location of the coils.

摘要： A lead screw actuator for displacing holder with a collimator lens in an optical scanning device has a home-position for accurately determining the position of the collimator lens. An anti-seize construction is provided to avoid the holder to get stuck against the home-position due to the friction between both surfaces.

摘要： An optical disc recording and/or reproducing device comprising a drive for rotating an optical disc around an axis of rotation, a movable optical pickup unit (5) and a frame (1) having at least one guiding rod (4) for guiding a displacement of the optical pickup unit (5) in a substantially radial direction with respect to the axis of rotation. The guiding rod (4) is provided with a protrusion (17) for restricting the movement of the optical pickup unit (5) when the guiding rod (4) is in a is in a predetermined rotational position. The guiding rod (4) is rotationally drivable by an electric drive motor in order to move the protrusion (17) for either releasing or blocking the optical pickup unit (5).
