Abstract

The research of high density optical storage system leads to the high density of tracks and pits of the disc. The track pitch of high density optical storage system is much more narrow than that of ordinary optical disc such as DVD. The first step in the production process of both pre-record data and recordable optical discs is mastering. Thus in the high density optical storage system the stable and accurate mastering performance is of greatest importance. This paper presents a control scheme that provides fast, accurate and stable mastering performance. Because of the high density of the track on the optical disc, the conventional control of mastering scheme is unfit for good mastering performance. In this paper we review the development of optical storage system and analyze the problems that may arise when the conventional control scheme is applied to the high density optical disc mastering system. In the proposed scheme, a new tentative control system is designed. The performance of the proposed tentative control scheme is shown by experiments in the high density optical disc mastering system.
