dc.description.abstract | Recently, DVD/CD compatible driver is needed for DVD and CD is widely used as a new optical data restoring device. The optical systems of DVD and CD driver are different because they have different optical feature. if only one objective lens is used, the change of an aperture or a dual focal length of the lens is required. This method, however, increases the namber of parts and results in loss of the power of laser light. Hence, we propose a dual lens actuator design that can read DVD and CD respectively. Albeit magnetic spring is important mechanism in the dual lens actuator design. there has not been the systematic approach to design the mechanism in the preceding researches. In this article, the guideway to design magnetic spring is presented by using the qualitative theoretical approach and the finite element analysis. | - |
