The 16x recording for DVD-RAM was achieved by using a newly developed faster servo system, implementing the CAV writing method at 11,000 rpm as well as by using a new writing strategy.
Hitachi and Panasonic dropped the traditional multi-pulse write strategy, and implemented the "castle" strategy, which was also used when recording at high speeds with DVD+RW media. The new strategy, combined with the new phase-change materials used in the DVD-RAM media, would allow high-speed recording.
Maxell has developed the BCM (Bismuth Coupling Material) recording layer for 16x DVD-RAM that achieved a shorter writing time with high speed crystallization in high temperatures. High temperatures while recording at 16x are due to the use of a 300mW laser.
The BCM material will also be adopted by the Blu-Ray media manufacturers. Hitachi Maxell will launch the new media within the year.
Hitachi LG also plans to begin shipping a 16x super-multi recorder in 2006.
