摘要
An optical pickup actuator is an objective lens moving mechanism that provides a means to accurately follow the disk displacement Recently,since drive speed and physical density of the optical disc have become higher, better performance and higher precision are required of the actuator. Moreover. small and thin design has become desirable. In addition, ii compact disk/digital video disk (CD/DVD)-compatible pickup may require different actuator design. In this paper. we introduce an optimal design method that complies with these requirements. Sample actuators are made with optimally designed parameters. The performance of the samples is evaluated and compared with simulated data. The results prove the effectiveness and validity of the proposed method. We expect them to be used in CD/DVD-compatible pickups.
