Paper Abstract

Rewritable optical disks require higher recording density in order to record HD-Video signal. Improvement in random accessibility is also highly recommended for realizing RTRW (real time recording requirement). In this paper, we propose a new addressing method which employs phase modulated(PM) wobble signal to encode a physical address for land/groove recording. We call this method as address in Phase modulated wobble (APMW). By using proposed new addressing method, we could increase recording density as compared with a pit addressed method such as applied in DVD-RAM and improve random accessibility as compared with that of DVD-RW.
