DVD+RW Alliance: 16x DVD+R standard before the end of 2004!
CES 2004 that is now taking place in Las Vegas was selected by DVD+RW Alliance to showcase its single-sided dual-layer DVD+RW/+R media and report the successful development of 16x DVD+R.
For the sake of justice I must note that CES 2004 exhibits supporting recordable single-sided dual-layer DVD+R were initially introduced as far back as in last October at CEATEC in Tokyo. The method of recording and playing dual-layer DVD+R is simple and known since dual-layer DVD-ROM: the second layer is accessed by optical refocus. Still the speed in case of this dual layer is only up to 1õ. But there´s full compatibility with DVD Video in place. The total capacity of such a disc is therefore increased from 4.7GB to 8.5GB. The drives supporting single-sided dual-layer DVD+R are expected in the market already this Spring.
Before the end of 2004 they also plan to widely promote the 16õ DVD+R recording. To do this, according to DVD+RW Alliance, the media rotation speed might be increased to 10,000rpm. Here we get closer to the physical media limits, so the 16õ should become the maximum for this standard.
Anyway currently DVD+RW Alliance is thinking over the final specs. The standard approval is expected early this Autumn, so the first 16õ DVD+R media might appear in the market in Spring 2005.
