Paper Abstract

In an optical disk drive, seeking and following servo guarantees correct track jumps and continuous read-out signals mainly through controlling the sled movement. Till now there are much more works and publications contributed to focusing and tracking servo than to seeking and following servo, which involves non-linear effects such as friction of the sled and thus is difficult to characterise. However, to enhance the performance of an optical disk drive, a close study of the sled system is necessary to improve the seeking and following control strategy. In this paper, experiments are conducted on a SONY CD-ROM drive and a physical model of the sled system is drawn from experiment data.
