Abstract
In this paper a miniaturized 1 inch actuator is studied and designed for optical disk drive (ODD) systems. In particular, it is adapted in an NFR system (K.H. Kim et al, KSPE, vol. 18, no. 8, pp. 174-181, 2001) using a SIL (solid immersion lens) system. It is a dual servo actuator, which consists of a fine actuator and a coarse actuator. Its actuating force generation method uses a VCM (voice coil motor). The fine actuator is composed of 4-wire suspensions and a bobbin wrapped by coils. The coarse actuator has coils and a V-groove guide system.
