Optimized disk structure and Ge-Tb-Sb composition for overwritable phase change compact disk

Optimized disk structure and Ge-Tb-Sb composition for overwritable phase change compact disk

We have investigated a disk structure and recording film composition suitable for the overwritable phase change compact disk. A high performance has been achieved at low linear velocity using the rapid cooling structure and the recording film composition of Ge 25 Te 48 Sb 27 .
