A wire-suspended objective lens actuator structure and a method of assigning current pathways. The lens holder on the actuator structure has a group of focusing coils, a group of tracking coils and a group of slant adjustment coils. The coils are connected to four conductive wires. A first conductive wire controls the focusing coil and a second conductive wire controls the tracking coil. Similarly, a third conductive wire controls the slant adjustment coil. The ground terminals of all three groups of coils are connected in parallel to a fourth conductive wire. The fourth conductive wire serves as a common ground terminal. The control terminal of each group of coils is connected to a differential voltage-output current amplifier circuit or a differential voltage-output voltage amplifier circuit. Hence, the focusing, the tracking and the slant adjustment coils can be driven by differential voltages.
