Abstract

Sector servo optical disk mass data storage system was designed. In this method each track is divided into 1024 sectors. Each sector consists of the preformated servo field and data field where data are recorded. One forth wavelength depth preformated servo field contains wobbled pits array from which tracking servo signal is generated. This tracking error signal is sampled and hold in the data field. This system has advantages of its compactness of optical drives and higly improved optical stability.
