- 論文の詳細を見る
We investigated Sb-based In-Sb as a material for high-speed recording that is capable of maintaining a highly stable amorphous phase. The crystalline phase of In-Sb is unstable at approximately its eutectic composition. After an aging test, InSb was segregated, and its reflectivity was reduced. For an Sb-rich In-Sb, we confirmed that its crystalline phase is stable and its crystallization speed is high. We demonstrated the feasibility of $16\times$ digital versatile disk (DVD) recording using 2T-period multiple-pulse strategy.
