  • 3D ACTUATOR FOR OTPICAL DISC SYSTEM
    Publication number: 20100271912
    Abstract: 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.

  • 3D actuator for optical disc system
    Patent number: 7779433
    Abstract: An optical pick-up actuator includes a lens holder having tracking and focusing coils which substantially extend in two parallel planes at a side of the lens holder. A magnet system cooperates with the tracking and focusing coils and is arranged separately from the lens holder and extends beyond the planes. The coils are arranged for effecting tilt through cooperation with the magnet system and may be provided at each of two opposite sides of the lens holder.

  • Displacement device with a modular system of displacement units
    Patent number: 5898243
    Abstract: A displacement device with a first part (1) and a second part (3) which are mutually displaceable in a displacement direction. The first part (1) comprises a number of contact bodies (7) which are pressed against the second part (3) against a pretensioning force which is present between the first part (1) and the second part (3). The contact bodies (7) are movable stepwise relative to the first part (1) and are also displaceable perpendicularly to the displacement direction. A stepwise movement of the contact bodies (7) causes the first part (1) and the second part (3) to be displaced relative to one another in the displacement direction under the influence of a friction force present between the contact bodies (7) and the second part (3), while the first part (1) and the second part (3) are supported in an accurate position relative to one another perpendicular to the displacement direction through a displacement of the contact bodies (7) perpendicular to the displacement direction.
