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.

摘要： An electromagnetic drive includes a drive plate disposed in a magnetic field. The drive plate includes a non-conductive medium with a first plurality of linear conductive elements arranged parallel to a first axis. The first plurality of linear conductive elements connects first and second electrical terminals supported by the non-conductive medium. The drive plate may be driven in the magnetic field along a second axis that is substantially perpendicular to the first axis when an electrical current of sufficient magnitude is passed through the first plurality of linear conductive elements.

摘要： A pickup for accessing moving storage media carrying substantially parallel information tracks has a carrier, an actuator with a lens and suspension wires extending from the rear of the carrier and joining the carrier and the actuator. The actuator is movable in the focus direction and in a tracking direction and has a substantially rectangular flat board carrying the lens and a counter weight. The flat board is arranged orthogonal to a focus direction and carries tracking and focus coils. The pickup has a magnet configuration connected to the carrier with at least two tracking magnets, which are arranged in the tracking direction at opposite sides of the flat board and extend orthogonal to the focus direction above and/or under the flat board, and with at least two focus magnets, which are arranged in front of and behind the flat board and extend orthogonal to the direction of the tracks. According to the invention, the lens is arranged asymmetrically in reference to an axis through a center of the flat board parallel to the direction of the tracks while the lens and the counter weight are symmetrically arranged in reference to the center of the flat board.

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.
