Gottfried/all....DVD stuff from the IOM Motley Fool board: Subject: MacIntouch @ Comdex on Optical Storage <<After years of debate in and out of standards bodies, the world of optical storage remains wracked by severe and potentially debilitating conflicts about next-generation technologies. Yesterday a group of top-tier vendors, including HP, Sony, Philips, Ricoh, Verbatim, and Yamaha, announced agreement on a new specification for future rewriteable DVD with a capacity of 4.7 Gb per side. The spec will be submitted to standards organizations next year, they said. In the meantime, they're pushing ahead with plans to deliver DVD+RW drives and media with a capacity of 3 Gb per side in the spring. The companies supporting the new spec have organized under the name DVD+RW Compatibility Alliance (DCA for short). But they mean compatibility with each other; barring a major change of direction by one camp or the other, there's no possibility of compatibility with DVD-RAM, a different rewriteable format that was endorsed by the DVD Forum and is now being promoted by other companies, particularly Panasonic and Hitachi. A big part of the promise of both DVD-RAM and +RW is that they'll make it easy and affordable to create discs readable in DVD-ROM drives, which are expected to become a desktop standard, like CD-ROM today. Unfortunately, current DVD-ROM drives, even the so-called second and third-generation models, won't be able to read DVD-RAM or +RW discs. The +RW camp claims that their solution will require relatively minor engineering changes in future DVD-ROM drives to achieve compatabilty, whereas accommodating DVD-RAM discs would require much more extensive work. (DVD+RW is apparently descended mainly from CD-RW technology, whereas DVD-RAM is based on the less common PD, or Phase-change Dual, format.) On the other hand, DVD-RAM proponents claim that their compatability problems with the new ROM drives are on the verge of disappearing as so-called "5x" drives appear in the next few months.In short, it's a mess, with no resolution in sight.. Whatever the technical merits, these conflicts disturb users and discourage them from committing to any of the choices; if that becomes permanent, none of the alternatives will ever be a real standard. That would be a real shame, because the idea behind both of the warring technologies - providing a low-cost, high-capacity, and high-reliability removable media - is pretty alluring. >> Regards, xxxxxxx still a long-term raging bull... who has never sold a share... ******************************************************************** This is exactly the reason I won't be ordering a DVD anything in my new computer next fall unless some of the smoke clears and there is quite a bit of standardization in place. Unlike some who post here, I don't believe in buying doorstops! Dave
