What is the difference between DVD and Blu-ray and we can finally buy Blu-ray Disc?
I do not know the difference between the discs and even if we should buy Blu-ray inventually as the switch from VCRs and DVD players.
Blu-ray uses a blue-violet laser as opposed to the red laser used on DVDs. This allows Blu-Ray to hold much more information about them to a DVD. This increase in the amount of information that can be stored on a disk allows you to set-movies high definition on a disk and not run out of space, Since the average HD movie take up about 15-20 GB of space. If you have not seen a HD movie yet i would suggest stopping by your local Best Buy or Circuit City and watching a Blu-Ray display. The images are sharper, brighter and more detailed than any DVD movie. That producers are trying to do is look the film closest to what you see in a real theater as possible, except for its tenth the size and in your home. Blu-ray may not be reproduced in a traditional DVD player, which means That will eventually need to buy a Blu-ray. However, all Blu-ray players can play DVDs, and climb the file to look better on an HD screen, 1080p So while you will get a new Blu-ray player to play HD movies, you can still see all your current DVD the same player, and will be reinforced. In essence, Blu-Ray will replace DVD as DVD replaced VHS and CD replaced the cassette.
