摘要： The invention provides an optical scanning apparatus for appliances for recording or reproducing information using an optical recording medium, said scanning apparatus automatically matching itself to the curvature of a curved recording medium or of a recording medium with axial runout without there being different wire diameters for the resilient support of the lens holder (LH) or other additional damping means or an additional control loop for this purpose. This object is achieved by virtue of an arrangement comprising coils and magnets being provided which has an asymmetrical magnetic field distribution which is provided for matching the orientation of a lens (L) in the optical scanning device to a curved recording medium or to any axial runout in the recording medium. The asymmetrical magnetic field distribution is achieved with magnets arranged offset laterally or with magnets (MS) which are bevelled on one side or with a focusing coil which is asymmetrically shaped or is arranged asymmetrically with respect to the magnets. The individual embodiments for achieving an asymmetrical magnetic field distribution can be combined with one another.

摘要： A suspension arm actuator for a scanning device includes a suspension arm which is designed as a two-arm lever having a first and second arms. The second lever arm includes a component for a magnetic drive for a swivel motion of the suspension arm. The component is arranged at a recess having the shape of a circular arc, with an inner leg of a yoke being permanently attached to a support projecting into the recess and forming a magnetic yoke, wherein the yoke is provided with a shell-like magnet on its outer leg in order to form the magnetic drive. A magnet for field optimization, which is magnetized perpendicularly in relation to the shell-like magnet, is arranged on the yoke in the region between the inner leg and the shell-like magnet to increase the sensitivity of the suspension arm actuator.

摘要： The invention relates to a suspension arm actuator for an optical scanning device, comprising a suspension arm designed as a two-arm lever and mounted between the lever arms such that it can be pivoted about an axis extending perpendicularly thereto. On its end side, one of the lever arms supports a scanning head and comprises an articulated region, preferably an elastically bendable region, for a motion of the scanning head in focusing direction and perpendicular in relation to the pivot plane of the suspension arm. The other lever arm is provided with a component of a magnetic drive for a swivel motion about the axis. In addition, the suspension arm actuator comprises a magnetic drive for moving the optical head in focusing direction. As a result, the suspension arm is designed such that the latter's lever arm that supports the scanning head is designed simply and without any further functional elements and is, therefore, reduced in weight. To achieve this, the magnetic drive for moving the optical head in focusing direction is allocated to the lever arm (II) which comprises a component of the magnetic drive for the swivel motion about the axis. The coils for the magnetic drives are, in particular, designed as printed coils.

Each suspension element has two parts, where a first part is connected to the carrier and a second part is connected to the body of the actuator. According to the invention, the suspension elements are constituted as suspension wires, where each suspension wire is folded, where the first part and the second part are constituted as a first side and a second side of the folded suspension wire and where the both sides form an acute angle with each other.

摘要： Actuator for an optical scanning device, having a focus lens mounted in a lens holder and having a damper base firmly connected to a mount, having a magnet arrangement arranged on the mount, and a coil arrangement interacting with the magnet arrangement, on a printed circuit board, for fine positioning of the focus lens, with the printed circuit board being connected to the damper base by means of elastically flexible suspension means arranged on both sides of the longitudinal axis of the actuator. It achieves the object of designing an actuator such as this in such a way that it has a reduced moment of inertia, because of a reduced mass. For this purpose, the printed circuit board is at the same time a mounting board for the lens holder, and the printed circuit board and the lens holder together form the moving part of the actuator.

摘要： The invention relates to a suspension arm actuator for an optical scanning device, comprising a suspension arm designed as a two-arm lever and allocated to an optical recording carrier. The suspension arm is, in known manner, mounted to a support between the lever arms such that it can be pivoted about an axis extending perpendicularly to said suspension arm. On its end side, one of the lever arms supports an optical head having optical components, in particular having an objective lens, while a magnetic drive initiating a swivel motion about the axis is allocated to the other lever arm. In addition, the suspension arm actuator comprises a magnetic drive initiating a motion perpendicular to this swivel motion and electric connections between a control unit arranged outside of said suspension arm actuator and the electrical and optical components. The invention solves the problem of designing such a suspension arm actuator such that said suspension arm actuator allows arrangement of an increased number of optical components while keeping or being reduced in its height. To achieve this, electric connections are established by means of line sections arranged at the suspension arm in a plane extending in transverse direction in relation to the axis spaced apart radially from the axis and spaced apart from each other, said line sections each being electrically connected to a contact element for connection of a control line running to the control unit.
