A streak-camera system for the observation of high-speed crystallization processes induced by laser irradiation in phase-change (PC) recording materials has been developed. A distinct difference in the time-sequential development of the crystallized region was observed in two different types of PC materials, i.e., Sb78Te22 (eutectic composition) and Ge2Sb2Te5 (pseudobinary alloy) films. Taking into account a thermal simulation analysis, the observed difference is interpreted in terms of the different crystallization process. It is concluded that Sb78Te22, which is a growth-dominant film, is suitable for high-speed high-density recording.
