Abstract

The demands of high data transfer rate and high recording density in optical disk memory device are being increased. In order to achieve high performance, lever actuator for optical disk is proposed. Firstly, the role of lever and structure are discussed and the flexure hinge is introduced to enhance the precise movement. Next is to present the magnetic circuit structure and concept design for the lever actuator. Finally, the dynamic modeling of the lever actuator is found and the analysis results are shown. Consequently, the lever actuator shows the possibility as a pickup actuator for the next generation optical disk.
