Abstract

The rewritable optical disk is expected as the key device for storage at the dawn of the full-scale multimedia age. It requires a large storing capacity so as to record and reproduce great amounts of data including motion pictures and audio information as well as data for computer processing itself. This paper reports land and groove recording^{(1) (4) (5)} and mark edge recording technologies⁽²⁾⁽³⁾on phase change media, the key role in realizing high capacity.
