Paper Abstract

New recording material with higher crystallization speed and higher thermal stability is required to realize a phase-change disc for higher data recording rate. We have developed a new phase-change material that consists of TbSbTeGe material based on eutectic composition. This new phase-change material improves the crystallization speed and the crystallization temperature simultaneously. We have achieved the practical use characteristic of data recording rate of 216 Mbps (6X-speed of Blu-ray Disc) by using TbSbTeGe new phase-change material.
