    Which would you buy? What are the pros and cons? Which do you think will come out ahead?

    I wouldn't buy any of them right now. Why? Because the companies themselves haven't decided which one to push.

    Btw, why did you stick holographic into the list? It isn't a standard it's a technology.

    for data storage.. blue-ray for now... in the future, holographic.

    for video.. dunno yet.

    I don't know much about this but from what i'v heard blu-ray sounds amazing. Sony and apple want blu-ray but Hollywood wants HD-DVD.

    B-DVD has more capacity than HD-DVD, 40% more.
    What is holographic?

    Holographic is a fancy hollywood theoretical technology that has not emerged from the dark window-less labs yet. I'm personally a blue-ray kind of guy but HD-DVD has already become standard in hollywood. Sony will push blue-ray though. I'm not digging holographic within the next 10 years. Maybe after that.

    No one has decided on Blu-ray or HD-DVD. Companies keep flip-flopping on the issue.

    Even the current dual-layer DVD (8.4GB) hasn't been made popular yet, why not we just focus on dual-layer DVD? 8.4GB shall be enough to record a good movie!

    How exactly is this? Isn't the wavelength of blue light 27% less than red light?

    HD-DVD can go up to 30GB, blue-ray can pack 50GB per layer on 1 disc, however, blue-ray needs a complete new production line, this will pump up its cost, while HD-DVD can be made on existing DVD line with minimum adjustment.

    google for it, i read it from cnet.com

    tried, no one gave an explination of why.

    Blue laser has narrower wavelength, so it can pack more info per squared inch.

    I am more than aware of this, as you can see from my previous statements. Well, just read my previous statements than you'd understand. Anyone else know where that number comes from?

    Dual-Layer is definetly made popular... who the hell uses single layer DVDs except for a bunch of white bellied, red necked, cousin ****ing hill billies?

    Just wanted to know if anybody got any GOOD stuff on Holographic storage. I did a project on it in 2004 but all I could find was mid-90s journal articles:frown:

    The tech is super amazing but where's the R&D? Anyone??

    We shall support HD-DVD or Blue-Ray DVD?
