20090161498 | Suspension arm actuator for a scanning device - The invention relates to a suspension arm comprising a suspension arm designed as a two-arm lever, said suspension arm mounted to a support such that it can be pivoted between the lever arms about an axis extending perpendicularly to said suspension arm. One of the lever arms supports on its end side an optical head having a focal lens and comprises an elastic region for initiating a motion of the optical head in focusing direction perpendicularly to the pivot plane of the suspension arm. The other lever arm is provided with a coil of a magnetic drive for initiating a swivel motion about the axis. In addition, the suspension arm actuator comprises a magnetic drive for initiating the motion of the optical head in the focusing direction. It solves the problem of designing such a suspension arm actuator such that the sensitivity of said suspension arm actuator is increased. To achieve this, at least one of the magnetic drives is designed with at least one printed coil which is provided with at least one layer increasing the magnetic field strength. | 06-25-2009 |
20090219652 | Actuator for access to strorage media - The invention relates to actuators on pickups for access to moving storage media. An actuator according to the invention comprises a circuit board which, in an edge region, has a metallization on its edge or metallizations adjacent to the edge on two or more inner or outer surfaces, suspension wires for connecting the actuator to a carrier being soldered onto these metallizations. | 09-03-2009 |
20090245070 | Suspension Arm Actuator For an Optical Scanning Device - 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. | 10-01-2009 |
20090249380 | Suspension Arm Actuator for a Scanning Device - 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. | 10-01-2009 |
20090274019 | Optical Scanning Apparatus for Appliances for Recording or Reproducing Information Using an Optical Recording Medium - 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. | 11-05-2009 |
20100103797 | PICKUP F0R ACCESSING MOVING STORAGE MEDIA AND DRIVE HAVING THE PICKUP - A pickup for accessing moving storage media, carrying substantially parallel information tracks, has a carrier, an actuator and suspension elements joining the carrier and the actuator. The actuator has a body and a lens and is movable in a tracking direction and in a focus direction.
