BLU RAy discs

there is this new technology called the "Blue Ray Disc" having a storage capacity of 20 GB for a single layered disc and 40 GB for a dual layer disc..this is revolutinising the age of optical media.....am eagerly waiting......DVD's are a thing of the past

Yup, its been in development a real long time and has been "around the corner" for the past 4 years.
Blue laser has a wavelength much shorter than the red laser which is used currenlty in optical media. Thus, it will be physically possible to have a lot more (read 2 or 3 times) "holes" and "mounds" on an optical disc than is possible by using the red laser. Effectively doubling if not tripling the capacity of such a disc.

But like I said, this technology is still far from the production stage.

I wonder what they are gonna do with all that space!! Isn't ther another one like Blu Ray which is 100GB...i don't remember the name

it is really good technology
but I hope that they don't screw it up by someone coming up with their own type

that is one of the reason I still prefer good 'ol CDs
whenever I give them to anyone I just know it will work

I think Philips and IBM are still fighting with their own standards...so that they get maximum mileage..

From what i got to learn from a friend (his id here is rash) is that microsoft has come up with some thing which will work with current set of players (Blu ray neede different player) & have storage & clarity more than that of the blue ray

Its called HD-DVD :-)
