On a microholographic disk the pit-land structure of a CD or DVD is replaced by microscopic volume gratings. These "microgratings" are holographically induced in the focal region of two counter propagating, highly focused laser beams: one beam is focused into the photosensitive layer and reflected back. The interference pattern of the incident and reflected beam results in a grating-like modulation of the refractive index of the storage medium. |

» Yeah.
That's huge, however, it's still a DVD and DVDs don't do 1080p :)

» DVD-sized
I dont think it's a DVD, just DVD-sized. But what I am curious about is the read speed. Having that much of data, I wonder if the reader for that discs can buffer that much...

» blu-ray
blu-ray is a dvd...
hd-dvd is a dvd...
all dvd means is Digital video disc.
That has nothing to do with resolution

Uhhh,
Doesn't DVD stand for Digital Versatile Disc? Meaning it is capable of more than just video? Yes, I know, I'm right. It's okay. I don't gloat. Also, I think DVD can contain whatever resolution you want them to contain. The textures contribute to filesize and that was the real drawback of DVD. Larger capacity spawned higher resolutions. F.E.A.R on DVD held very high resolutions for PC, however, if you've ever burned a DVD movie you see how pixel size and quality correlate with file size.

they are reffered to a both, and you made absolutly no sense down at the bottom... file size has nothing to do resolution, there are many factors

Uh yea the file size does matter, why do you think that they use blu ray and hd dvd for hd. cuz theres more memory storage and why do you think that hd videos on gametrailers are bigger than the standard videos.

» Lotsa dumb ppl above me gosh!
Its Digital Versatie Disc, and its a brand name. Blu ray is NOT a DVD nor is HD-DVD. Bluray is bluray disc. Also the higher the resolution of a video, the more mbytes. therefore more space

» DVDs can do HD
When HD-DVD players first came out people were burning DVDs with HD videos and playing them on HD-DVD players, as all it comes down to is the codec support and resolution support. It's just that DVDs can't hold enough data for a whole movie in HD.

» big size
sure it can cram alot of memory. I think that they just coppied BlueRay and made it even better,.,. how come we didnt here about this before vlueray and Hd-DVD,.,.
and after all that,., just imagine the price. BlueRay is 5-15 bucks more than standard DVD so this new DVD will probably be $45, possibly even more,.,.
im sticking with Blueray

Just call it a disc. Its not a DVD. Anyway I dont think it would be necessary until TVs start dishing out way more than 1080p, which wont happen for a awhile.

» Yeah
Yeah, I mean cmon, Bluray players are already in 5 million peoples homes, and by the time these come out im sure it will be 20 million. I don't think 20 million people willl suddenly go over to this new dvd disk and because it can hold more.

» You wont see this long...
What you people forget is the following:
1: This is just a technical post, not an actual product
2: Till you see this as a product to purchase, probably few years will pass
3: There's nothing said about production at all
4: Will it be reliable enought? Tiny scrateches on surface and you can trash the disk?
5: Is it really needed? Well, 1080p is the current max resolution for the standard called "FullHD". FullHD Movies perfectly fit on blue ray. So movies wont need the added space. Maybe for backup purpose this is nice, but not needed.
and so on...

» blu-ray
the max amount of data a blu-ray can hold is 150gb because 25gb fit on one layer, 3 layer max right now on one side, dual-sided, do the math and a total of 150gb.

» only tecnological research
***** men, is a university project, no a monster like sony, philips or thoshiba, those students maybe in the future work for this companies or found one.
this tecnologie is no founden in taking diferent lasers colors like HD-DVD or Blu-ray is microholographic, the problem is take 50 layers to research 500 GB, to primitive by standars but still a prototipe.
Holographic tecnology is still in investigation in the Hard disck too

» No need to buy a blue ray and hd players anymore....
I've read in another article that it will run perfectly with your current dvd players so you dont have to spend $100's on blue ray or HD players.

» regular players are not designed for HD video files
Even if something crazy like that did happen, a normal dvd player or upscaler won't have the correct firmware and hardware to handle HD video on the discs themselves, let alone being able to read them. And with regular players, not even HD capable outputs.

» Doesn't anyone know about HVDs!?!?
HVDs can hold a lot more then 150GB...
So far HVDs (Holographic Versatile Disc) can hold 300GB of information and in the future may hold up to 3.9 terabytes of data. (Thats a S**Tload of space!!!)

Yep I heard about HVD about a year 1/2 ago. Back then it would hold 1.6 terabite. (terabite+1000 gigs)
