Paper Abstract

The addition of Al increases the temperature and activation energy of crystallization of the fast-growth type Sb70Te30 recording film so that the archival stability will be improved. Meanwhile, the addition of Al increases the temperature and activation energy of melting of the Sb70Te30 recording film so that the local melting of the crystalline Sb and Sb2Te3 phases will be suppressed. The pulsed laser powers required to trigger crystallization, melting, and ablation of Sb70Te30 recording film increase with increasing Al content indicating the increased stability of the non-crystalline phase, in the meantime, the increased melting and ablation powers indicating the Al addition could increase the melting temperature and prevent ablation effect of the Sb70Te30 recording film.
