- 論文の詳細を見る
Rewritable discs based on Ge-Sn-Sb phase-change compositions that combine high crystallization rates with good archival life stability were designed. The crystallization rate can be varied from $2--16\times$ digital versatile disc (DVD) speed by variation of phase-change composition. The rate increases with decreasing Ge concentration and is dependent on dopants. For high-speed discs based on these compositions, back growth is substantial, but can be diminished by designing an efficiently cooled stack. By doing so, phase-change optical recording at $10\times$ DVD rewritable (+RW) with 9% multitrack jitter is demonstrated using a 2T-period-based write strategy.
