Abstract

In an optical disc archive system, disc insertion process is an important part. Furthermore, dynamic analysis with the contact area between multi-bent leaf spring and a disc should be considered because the contact area is moved when the disc is inserted into the cartridge. In this paper, a finite element model of disc insertion was constructed based on dynamic characteristics, vertical stiffness, and dynamic response. The disc insertion model was validated with the experimental results. To identify the dynamic response of the disc induced by the changed contact area, applied force to the disc and the stiffness of the multi-bent leaf spring were analyzed. As the results, the factors which cause the failure of the disc insertion were investigated.
