The Technology Of Blu Ray
Blu-ray technology was developed using a blue laser to read and write to a disc. The wavelength of the Blu-ray is smaller, so much more information can be recorded on Blu-ray discs. Standard DVDs are burned using a red laser and cannot hold as much information as a Blu-ray disc.
Blu-ray discs can store a significant amount of information. They can actually hold as much as six times the amount of data a two-layer DVD can hold, and as much as ten times the amount of data as a two-layered DVD. This allows the picture and sound quality embedded in the disc to have a much greater quality than those on a DVD.
Blu-ray discs will not play in DVD players. Remember, DVD’s are read by a red laser. A blu-ray must be read by a blue/violet laser. The red laser in a standard DVD player cannot read the data on a Blu-ray.
If you plan on watching 1080P high definition movies you will have to upgrade to a Blu-ray player. This will allow you to see great high definition movies the way they were meant to be seen.
Don’t be confused by Blu-ray and HD-DVD. HD-DVD players use a different type of blue laser that cannot read Blu-ray discs. Blu-ray discs cannot read HD-DVD’s either. The technology for each type of disc is completely different, and Blu-ray offers the highest quality audio and video.
This is the perfect time to outfit a new home theater room. You no longer have to buy a DVD player because Blu-ray players can play standard DVDs and new Blu-ray discs. It will not harm your DVD format or alter the disc to play it on a Blu-ray player.
Standard DVD’s will look better when played on a Blu-ray. They will not have the same quality as a Blu-ray, but the picture quality should be improved. You will most enjoy viewing high definition Blu-ray movies in your Blu-ray disc player.
