Design of alignment and positioning structure in huge-capacity optical storage system

In order to meet the development requirements of high density, high capacity and high integration in the field of optical storage, a new scheme for optical recording system is supplied in this paper. At the same time the methods about disc alignment, position and clamping are discussed in details. The principle of flexure hinge is adopted. The results of experiments show that the scheme is feasible, and the setups for optical discs can meet the requirements.
