    • 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.

    • An optical pickup and optical recording or reproducing apparatus incorporating such an optical pickup is recommended, which comprises an adjustment means to adjust the actuator plate of the optical pickup, which holds the objective lens, by moving the actuator plate AP on a straight reference surface arranged in the slide base of the optical pickup to a position as defined by alignment equipment to compensate tolerances between traverse mechanism and disc motor. The adjustment means is a screw for moving the actuator plate on the straight reference surface inside the slide base against a counter spring and the alignment equipment is formed by the optical pickup, which irradiates a light beam to an optical disc inserted into the optical recording or reproducing apparatus and receives a return light from the disc as well as means for moving the optical pickup radially of the spinning optical disc. The proposed arrangement allows less tight tolerances of single members and requires only little outlay, because the optical pickup requires a small number of single members to assemble an optical pickup for reading of information from and/or recording of information to a disc.
    • 推荐包括这种光学拾取器的光学拾取器和光学记录或再现装置,其包括调节装置,用于通过将致动器板AP移动在布置的直线参考表面上来调节保持物镜的光学拾取器的致动器板 在光学拾取器的滑动基座中到由对准设备定义的位置,以补偿横动机构和盘式电动机之间的公差。 调整装置是用于使致动器板在滑动基座内的直线基准面上抵靠反弹簧移动的螺钉,并且对准设备由光学拾取器形成,该光学拾取器将光束照射到插入到光学记录中的光盘上, 再现装置,并接收来自光盘的返回光,以及用于在旋转光盘径向移动光学拾取器的装置。 所提出的布置允许单个构件的较不严格的公差,并且仅需要很少的费用,因为光学拾取器需要少量的单个构件来组装用于将信息从信息读取和/或记录到盘的光学拾取器。

    • The invention relates to an optical scanning device for an appliance for reading and/or writing to optical recording media, having a movably arranged optical housing with integrally formed slide faces for holding a support which is provided with mating slide faces, can be adjusted about a virtual axis and has a scanning head, having at least one adjusting screw which is supported on the housing, acts on the support, bears against the edge of an opening made in the housing, penetrates said opening with its threaded shaft in the direction of the support with play and can move in the opening in a transverse direction, and having at least one spring means which acts on the support on the side of the slide faces which is remote from the adjusting screw and tensions said support against the slide faces of the housing, and to an appliance having the optical scanning device. It achieves the object of designing the mounting arrangement for the scanning unit in such a scanning device such that an adjusting movement is effected gently and smoothly. To this end, the adjusting screw acts on the support at a variable angle and changes its angle with respect to said support in the event of a screw movement to prompt an adjusting movement from the support.
