Abstract
We found two key attributes of cycle stability for phase change erasable disc media. One is nitrogen modified active layer of GeTe-Sb2Te3-Sb system. The other is the combination of dielectric material of ZnS-SiO2 mixture and SiO2.
The disc media having the modified active layer and ZnS-SiO2 dielectric layer show wide tolerance for laser power and long life of more than 60 years. New disc construction shows two million overwrite cycle stability of BER characteristics.
