发明名称 Optical disc record system and method, and an optical pickup actuator unit for such a system
摘要 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).
