Display technology rapidly grew to an image that us two times as well as DVD-quality video. The problem was that DVDs can not store enough information to HD-quality video and sound, suitable to date. New technology has a DVD that can store up to five times more information than before. This new technology comes in two sizes called Blu-Ray and HD DVD. These two formats were created separately and they currently compete with each other. They both use similar technology to HD-quality video and audio, but they do have a number differences.The technology behind the two formats is based on the same optical technique that regular DVDs use. A laser is directed at the surface of the disc and reads the digital information is converted to video and audio. Blu-Ray and HD DVD incorporate a new colored laser that can be more focused on a smaller area of the disk. This may there be more information packed on the same size disc. It is like a turntable with a smaller needle and lines are tighter together just moved to the center, allowing more space to the exterior for more information. The reason for the fact that the data fit the same size as a DVD disc so that all optical discs created with older technologies will fit into the same reader. So a Blu-Ray or HD DVD player plays CD, DVD and their own discs. Because of their competition are no players that will play Blu-Ray and HD DVD.The main difference between the two formats is simply a matter of storage. HD-DVD can store 15GB and about three times as much as a DVD. A Blu-ray disc can store 25GB which is about five times as much as a DVD. Both have the same video resolution as of now, but Blu-Ray has the potential to improve the video store when available. For now, extra space is used for film extras like behind the scenes segments. Only time will tell whether these formats will merge or fight it out until the end. History has taught us that a format usually prevails.

HD-DVD offers the same technology, although it is unable to hold as much information as Blu-ray. Developed by Toshiba and NEC, it is able to take three times as much data as traditional DVDs. While this may be less than Blu-ray, the data capacity of HD-DVD is still higher than the amount needed for major blockbusters in high definition viewing.

Both Blu-ray and HD-DVD use a new type of laser which improves as the standard DVD uses. While older, standard DVD models use a red laser to transfer the content from disc to play to the screen, these two technologies use a blue-violet laser instead. The main advantage of using blue-violet lasers is that they are a shorter wavelength than red lasers. This means that they can be addressed with a much higher percentage of accuracy. If you the differences between these two formats can see but little, in short, Blu-ray is able to more information than HD-DVD, but keep HD-DVD is much longer and still holds an appropriate amount for all applications currently on the market. Both formats use blue-violet lasers to read the information better. The biggest question is what format will end at the top. Blu-ray has the added advantage that it is supported by some major players in the film business. Seven of the eight major Hollywood movie studios have released movies in Blu-ray format's, while five of these films are available exclusively on Blu-ray. HD-DVD has the support of some major manufacturers of consumer electronics, but does have some ground to make up with production companies. However, with the added experience in the production of more and more consumers are familiar with the name, it is very possible for them to pull ahead. The race to the top home-entertainment format will continue on and consumers will just have to wait to see which wins. In the meantime, players are available for both formats and some manufacturers have players that meet both formats. ~ Ben Anton, 2007
