Abstract:
1. An objective lens driving unit, the objective lens driving unit comprising: a moving structure to which an objective lens and a driving coil are operatively installed; a static structure comprising a magnetic circuit corresponding to the driving coil; suspension wires each comprising a first end operatively connected to the static structure and a second end operatively connected to the moving structure, wherein the static structure supports the moving structure through the suspension wires; and first and second circuit boards operatively installed to the moving structure, the first and second circuit boards comprising wiring layers, wherein the wiring layers comprise first terminals to which the driving coil is connected and second terminals to which the second end of each of the suspension wires is connected, wherein two adjacent terminals from among the first terminal and two adjacent terminals from among the second terminals in the wiring layers are disposed alternately such that the two adjacent terminals from among the first terminals are not aligned along any cartesian axes and the two adjacent terminals from among the second terminals are not aligned along any of the cartesian axes.
