What is a Blue Ray Disk?

I beleive it is the newest form of DVD. Some kind of high definition DVD, like HDV TV. Beter resolution and clarity. They are usually higher priced. I saw a blue ray DVD player at Best Buy for $999.

it is not a dvd or a cd but it is completely different from those it has very large space like 160gb in a small disk my friend and the partitions in this disk are maid very small and so they are a bit costly.

I had to look it up. I'd seen one commerical that mentioned it and had no clue either. It looks like it's going to be the next step up from DVD's. It holds something like 25gb instead of the normal 4.7gb that DVD's hold now. Should prove interesting. You can read more about them here: http://en.wikipedia.org/wiki/Blue_ray_disk

Its a high capacity dvd disc. I think it has around 10 times the capacity of existing dvd discs right now.

this disc contains 25 Gb sapce of data. it means you can now write ur data of 25 gb ON ONE DISC.
