Phase-Change Media for Ultrahigh-Speed Digital Versatile Disc Recording

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