HD-DVD and Blu-Ray

the basic diffrence between HD-DVD and blu-ray is just in the reading and burning date technologie . While HD-DVD use violet laser-rays to burn to 15Gb in one disc ( 30Gb if use both sides of the disc ) the blu-ray is capable to storage to 50 GB ( 25 Gb both sides ).

if you dont know the blue laser ray has a smaller wavelenght then violet laser rays so, the burning point is smaller and like so is required less space for information bit.

wow, this is insane! I could actually backup my HDD on just 2 of these...! But I wonder how much it will cost now? I will probably wait next 2 years for lower price, and then get on it when it becomes cheap and available to us all...

oh yeah they aren's cheap indeed .. maybe 2 years the preice get lower.

Actually the prices will not be all that bad, the Sony Playstation3 will utilize blu ray for their games and Sony has already confirmed the price of each game will remain between $40-60. For that amount of space I think its a decent deal.

Oke, this are 2 cool things, but the question is, wich of the two are they gonna use worldwide, cus if they would use both, it would create a problem for much of us. You can't buy both, that would be very expensive, and otherwise the firms have to make all movies, games etc. in two different versions.
So I think, they have to choose one, but wich? That depends on the price and quality. I know the BR has more capacity, but does anyone know, how expensive they are gonna be?

Not neccessarily Moody because in todays business world the dvd media is spread far and wide not only for movies and games but for use in direct to dvd cam corder recordings and so on, so both of these new technologies can easily be incorporated into the products we have and maybe even split of into seperate catagories or become rivals for example in the video game industry.
But i think that the old negative saying "size does matter" will definitely play a major role in which medium gets more sales, especially if they are both resonalby priced i will be gettting the Blue Ray.

I've heard just a tiny bit about this before. Great idea if you ask me. The more stuff we can pack onto DVDs, the more the film industry will charge for them (because, with this new technology, really bad movies can have over TWICE the lame commentary as they do now).

Really though, seriously, for the more practical uses, I'm all for it.

I've been wondering about this for a while.

Since the 'gap' between to burned bits is getting smaller, doesn't that make the disc more vulnerable to scratches? Because the distance between two bits getting smaller, if a scratch occurs, wouldn't that make more bits not readable?

I know modern disc players have a builtin piece of error detection and fixes it (somehow). But with such type of discs wouldn't there be too much 'damage' to the disc even with a small scracht so the error detection can't cope with it?

I've been reading up on this through reports from google news alot recently. It appears that blue ray may be the one which has the edge right now. As of the moment it has about 70 percent of Hollywood (with the most recent being Paramount pictures and soon to be Warner Bros putting out support.

Lines are being drawn. On the one side you have Sony, with Dell, HP and Apple with others supporting blue ray, while Toshiba has Intel and Microsoft backing them. Both Intel and Microsoft share the vision that digital videos, pictures, audio, etc. should be kept on home servers and transfered throughout the household. They would both benefit due to the notion that they will probably be the ones selling the hardware and software for these future home servers. The Blue Ray disks, however, have heavier DRM (digital rights management) that the Hollywood companies love, ensuring that the DVDs cant be ripped unless permission is given, which might be unlikely. This gave Microsoft a reason to put their support behind HD DVD since they would have an easier time porting the data to home computers as the thinking goes. Plus, the XBOX 360 would not want to be paying royalties to sony Blu Ray for the next generation of games.

Would this mean we have to buy 2 different players? I hope not. So if one movie firm says: we are going to use BR, then we have to buy a BRplayer if we want to see this movie. But then, if another firm says: We are going to use HDDVD then we have to buy a HDDVD reader to see that movie. And if my friend has a BRrecorder and I have a HDDVD player I can't watch his videos?? Wouln't that become a great problem....i really think they have to choose one.
