An optical disc record system comprising an optical pickup actuator unit for transferring data to and/or from a rotating optical disc. The optical pickup actuator unit comprises a fixed part (1) and a movable part (2) carrying an objective lens (4) for focusing a light beam on the optical disc. The movable part (2) is connected to the fixed part (1) by a number of substantially parallel elastic suspension wires (5). The movable part (2) is provided with a number of coils (8, 9, 15, 16, 17) of electrically conductive wires, which coils (8, 9, 15, 16, 17) are at least partly present in a magnetic field generated by magnets (10, 11, 18). At least one electrically conductive stranded wire (22, 23) is present between said fixed part (1) and said movable part (2) in order to feed electric current to at least one coil (16, 17).
An optical disc record system comprising an optical pickup actuator unit for transferring data to and/or from a rotating optical disc, which optical pickup actuator unit comprises a fixed part and a movable part carrying an objective lens for focusing a light beam on the optical disc, which movable part is connected to the fixed part by a number of substantially parallel elastic suspension wires, so that the movable part can move with respect to said fixed part in a plane substantially perpendicular to the longitudinal direction of said suspension wires, and which movable part is provided with a number of coils of electrically conductive wires, which coils are at least partly present in a magnetic field generated by magnets attached to said fixed part in order to drive said movable part relative to said fixed part, wherein at least one electrically conductive stranded wire is provided between said fixed part and said movable part in order to feed electric current to at least one coil.
An optical pickup actuator unit for transferring data to and/or from a rotating optical disc, which optical pickup actuator unit comprises a fixed part and a movable part carrying an objective lens for focusing a light beam on the optical disc, which movable part is connected to the fixed part by a number of substantially parallel elastic suspension wires, so that the movable part can move with respect to said fixed part in a plane substantially perpendicular to the longitudinal direction of said suspension wires, and which movable part is provided with a number of coils of electrically conductive wires, which coils are at least partly present in a magnetic field generated by magnets attached to said fixed part in order to drive said movable part relative to said fixed part, at least one electrically conductive stranded wire being provided between said fixed part and said movable part in order to feed electric current to at least one coil.
A method of transferring data to and/or from a rotating optical disc using an optical pickup actuator unit, which optical pickup actuator unit comprises a fixed part and a movable part carrying an objective lens for focusing a light beam on the optical disc, which movable part is connected to the fixed part by a number of substantially parallel elastic suspension wires, so that the movable part can move with respect to said fixed part in a plane substantially perpendicular to the longitudinal direction of said suspension wires, said method comprising:
