Abstract
PURPOSE:To enable the device with high reliability, by making the pickup main body toward three coordinate axes movable independently. CONSTITUTION:When the permanent magnet 7 is magnetized, magnetic lines go toward the arrow C at the part located with the voice coil 4, and the magnetic lines go toward the arrow B at the part located with the coil 12. Thus, when electric current flows to the voice coil 4, the force toward z is caused between the optical pickup main body 2 and the magnetic circuit 13. The optical pickup main body 2 is lighter than the weight of the magnetic circuit 13 and connected to the magnetic circuit 13 via the support 5 rigid toward x and y and soft toward z. Further, the circuit 13 is connected to the frame 11 via the support 10 soft toward x and y rigid toward z. Thus, most of force toward z caused between the optical pickup main body 2 and the magnetic circuit 13 is used to displace the optical pickup main body 2 toward z and the magnetic circuit 13 is not almost moved.
