Let's address some of the points in your DVD DVD: see digital versatile disc.

Type of optical disc. The DVD represents the second generation of compact-disc (CD) technology. article ("DVD's Death Sentence?," page 46, April 2000) in order of their importance. Holographic See holographic storage. technology is actually very interesting. It was very interesting when we first saw it over 25 years ago when it was being developed for tape applications. We saw a lot of excellent demonstrations. The capacity potentials were breathtaking. Unfortunately, we never saw an economic, shippable product.
Does this hold true for the current version of holography? We doubt it. In fact, if we are very confident that, in three to five years, we'll see a real product, it will be expensive but real. Current projections are that it will take another three to five years for it to become cost effective.
The reason DVD hasn't eclipsed CD has absolutely nothing to do with shipping product and a promised "better" product. The industry had a vision in 1995 for the next generation storage solution. The content development, computer manufacturing, and storage industry hoped that, in the blink of an eye, we would move to the bigger, better solution. The industry believed it and forecast some breathtaking growth. Market analysts bought into the story and, suddenly, they were forecasting humongous sales for DVD. Manufacturers believed the forecasts and so did the media. When the industry experts' forecasts weren't met as was projected, people started to grumble that DVD was a failed concept and we all looked around for someone ... anyone ... to blame. Of course it was the manufacturers' fault.
There are over 60 million CD drives in use today around the globe. They cost almost nothing for the OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and to install in a system. CD-RW (CD-ReWritable) The only rewritable CD technology. CD-RW disks look like other CD media, but with close inspection, they have a more polished surface with a very dark blue-gray cast. drives that are capable of writing -R and -RW media cost OEMs under $70. Media is basically free--$l-$3 and, surprise, for about 80 percent of the moving of data that we all do, this is sufficient. With these economic factors in place, do you feel everyone in their collective right mind is going to throw out a good storage solution for a bigger, better solution?
Recently, we were talking with a government IS manager who was weighing whether he should stick with the old tried and true MO or move to DVD. His concern was that he had to have a storage solution he could be assured would be readable in seven to ten years.
We couldn't absolutely guarantee him that, in ten years, the Years, The

Microfilm and Microfiche and that technology has been around since before the computer, but we advised him to look at the prime movers The Prime Movers were a blues band based in the Detroit area, formed in 1965. Robert Vinopal left soon after the band's formation and was replaced by Jack Dawson. James Osterberg, who would later be known as Iggy Pop, took over the drums not long after. for DVD. Not the drive manufacturers, but the entertainment and computer industries. They want the high capacity, low cost, universal storage solution for business, education, and entertainment applications.
In a perfect world, the DVD standards would have been developed and approved all at one time and manufacturers would have immediately produced and shipped the -ROM, -R, and -RAM products and the "discussion" would have ended. Unfortunately, we don't live in a perfect world.
The fact is that the standards do exist today, including the ability to write media and exchange it across all devices. Products are shipping -ROM, -RAM, DVD players A stand-alone device that plays DVDs. It contains a DVD drive and the electronics to decode the digital video. The device may play only manufactured DVDs, or it may be able to play DVD-R, DVD-RW and DVD+RW discs. DVD players are cabled to a TV or home theater system for display. , and DVD recorders (1) A recordable or rewritable DVD drive that is connected to the computer. It may be an internal or external device. See DVD drives, DVD-R, DVD-RW, DVD+R and DVD+RW.
(2) that will allow users to move rewritable discs from -RAM drives to any of these other devices. Is the media backward compatible Refers to hardware or software that is compatible with earlier versions of the product. Also called "downward compatible." Contrast with forward compatible.
backward compatible - backward compatibility to every -ROM drive that is being used today? No!
