    Forget Blu-ray and HD-DVD, I'll wait to go holo.

    So Blu-Ray DVDs can hold 50 gigabytes? Big deal. A holographic disc can store 30 times as much data. Stuck in the lab for decades, the mother of all memory is finally available, thanks to a gel-like film developed by InPhase Technologies. Whereas a DVD holds information on its surface and on a layer below its surface, a holographic disc packs data throughout the gel at every point where two laser beams cross. And its fast: A single laser pulse etches one million bits, for a write speed nearly four times that of Blu-ray disc drives. Plus, the new gel is durable enough to last at least 50 years. The first commercial product, Maxell's 300-gigabyte discs, are meant for professional archiving, such as TV stations need. Expect consumer versions in two to three years. By 2010, discs will hold 1.6 terabytes and may eventually reach 100 terabytes.

    How it Works

    Holographic drives record information onto discs with blue lasers similar to Blu-ray, but first they use a beam splitter to send the light in two directions. One part, the signal beam, passes through a series of micromirrors, which deflect certain sections of the laser, turning it into a checkerboard pattern of dark and bright pixels representing 0s and 1s, respectively, of the data you're saving. When that beam intersects with the other half of the laser, the reference beam, the overlapping light waves react with the light-sensitive gel to burn a 3-D pattern, or hologram, onto a disc. Adjusting the mirrors changes the intersection, so holograms can overlap at different angles, packing more bits into one area.

    Data Disc------------------Capacity--Writing Speed--What Fits
    Holographic (2010 version)--1.6 TB----960 Mbit/sec.--400,000 songs
    Blu-ray---------------------50 GB----36 Mbit/sec.---12,500 songs
    HD-DVD--------------------30 GB----36 Mbit/sec.---7,500 songs
    DVD-----------------------8.5 GB----27 Mbit/sec.---2,375 songs
    CD------------------------0.7 GB----7.9 Mbit/sec.---175 songs
    I'm perfectly fine with plain DVDs at the moment for movies, but this holo disc thing does have me a bit impressed. I'm looking forward to seeing its potential towards video games and TV shows. Just think, entire television seasons on one disc as opposed to 3-5 discs sets. Never having to hear the likes of graphic *****s like Factor 5 complaining that discs aren't providing enough room for their video game graphics. Its music to my ears.

    What does everyone else think?

    Not sure about holo, but I think Blu-Ray and HD-DVD are doomed. People just upgraded from VHS, and aren't ready to upgrade again. Factor in a format war, and soon these will be gathering dust in a pile of laserdiscs.
    That's my jacket!

    I must be living in the past, Up until today I had never even heard of blu-ray till I saw it advertised on the new casino royale poster saying available on dvd and blu ray from the 19th

    I am quite content with dvd and hope dvd remains strong for many years to come

    I'm sticking with DVD, good enough for me. Easier to pirate.

    Holo shmolo, thats what I say. I can see HD-DVD taking over since most things are headed that way, but not for a few years.

    Yeah I just changed over 8 years ago.

    I've been holding off on HD DVD and Blu Ray too. Mainly because of the cost but also because of the uncertainty. But now that there is a combined HD-DVD and BluRay player I don't feel as uneasy; that unit is still way out of my budget at $1000+. When all of this gets sorted out and the prices drop, I'll consider investing, but until then I'll just stick with regular(SD) DVD.

    I recently just purchased a new DVD player, the Sony DVPNS75H, which supports HDMI and upcoverts to 720p or 1080i (I actually received this player today). This dvd player connected via HDMI to my Samsung HDTV sports a super sweet picture, much better than the SD players. I was skeptical at first, as far as the upcoverting goes, but I read stellar reviews on this player and decided to try it out. Shortly after setting it up, I became very impressed. The new setup, and then hundreds of dvds that I have now, should easily last me while this HD-DVD/Blu Ray and eventual Holo mess sorts itself out.

    I saw the article in my subscription copy, and I've seen them pimp these concepts before, touting them as the next big thing when they're not all that far along and have no industry support yet and the drift off into the ether. This one I suspect will be one of those because of the precision needed for the dual-laser system and speed, plus the disc being gel-based means it's encased in a housing that looks a lot like a floppy disk's housing, which is more expensive.

    Meanwhile, you can now buy a gig of MicroSD flash memory off for $10 that's the size of a pinky finger's nail, there's a tablet PC coming out later this year that uses 32 gig of flash memory INSTEAD of a traditional harddrive - this means no moving parts to wear out or break. And supposedly, one of the major harddrive manufacturers is about to start marketing a harddrive that's pure flash memory that can be installed in any standard 3.5" floppy bay.

    So while we're currently suffering a format war between Blu-Ray and HD-DVD, flash memory is an up-and-comer that could make any optical storage system obsolete even before we get these holographic discs.

    I personally don't give a crap about any of 'em since I don't have equipment to make use of high-res stuff anyway, but if I did, I'd probably get the HD-DVD add-on to the Xbox 360 since it can be used with the game console OR apparently it can be hacked to work without it, a $200 HD-DVD player.

    Gel based? wonder where they got that idea? Remember the gel-packs on Star Trek Voyager?

    I'm sticking with regular old DVDs. I don't think HD-DVDs and Blu-rays will last. I just read a great Kevin Smith quote regarding HD-DVDs and Blu-ray in a magazine. I'll share it with you guys.
