PROBLEM TO BE SOLVED: To miniaturize the constitution of an optical pickup device by connecting terminals on the ground side with each other, in each driving coil of each biaxial actuator. SOLUTION: Optical lenses 16, 17 are operated by moving in the focusing and tracking directions by biaxial actuators 14, 15. With a driving current supplied to the focusing driving coils 1, 3 in each actuator 14, 15, coil bobbins 21, 29 are operated by moving in the focusing direction. In addition, with a driving current supplied to the tracking driving coils 2, 4, in each actuator 14, 15, the bobbins 21, 29 are operated by moving in the tracking direction. In this case, the ground terminals of the coils 1, 3 are connected with each other, as are those of the coils 2, 4. |
