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.
