Hi,
I hope all of you have heard of blue ray disk. Is is the advanced and newest form of DVDs but it looks like a normal DVD. It can store up to 50Gb of data. But it has not become very popular till now. Maybe because of the fact that blue ray discs and blue ray drives are quite expensive. And I think only Dell provides Blue Ray Drives with it's laptops.
I was just wondering how many of you people use blue ray. So, if you use blue ray disks please reply here and share your experience.

Actually a Blue-ray disc (BVD) is quite different from a DVD. DVDs and CDs are accessed using a red laser, while Blue-rays are accessed and burned using a blue laser (hence the name Blue-ray). This makes a difference because the red laser has a wavelength of around 650nm (nano-meters... very small), while the blue ones have a wave length of around 405nm. This enables the pits data is burned into be much closer together, saving room inside the disc. If I remember correctly, the blue laser also burns deeper into the disc than a red laser does. A standard Blue-ray can only store 25Gb, while a Dual Layer Blue-ray can store 50Gb. I use Blue-rays for my PS3 (because PS3 games are stored on them) and blue-ray movies when they are better priced.

It can be faster, however usually the movies cost much more than their dvd versions ($30-$50 for a BVD compared to a $15-$20 dvd) but the quality is much much better. The speed actually depends more on the player/reader than the discs. The speeds on the packages of writable media are usually speeds they tested the disc to perform optimally at, and because of that they add a byte or 2 to the beginning of the disc that keeps most software from writing faster than that (there are some ways of getting around it however.) Right now, because of the large difference in the size of information, a Blue-ray at 4x would technically be faster than a dvd at 4x, because more information is written in about the same amount of time.

That is also a big reason why I'm waiting. Price is a big factor. Thanks for your response. Have a good day.
