Abstract

This paper describes an unique mastering scheme to form the Land-Pre-Pit address along with the groove. The scheme expands the resolution limit and gives other advantages in the disc manufacturing. The authors produced the disc applying it on a 351nm mastering apparatus and confirmed the realization of 20 GBytes disc capacity per the DVD size. The scheme can be inherited in the future mastering using the shortened wavelength or the electron beam.
