Movie Playback From 1TB Holographic Disc 623

Posted by timothy from the floppies-were-so-awesome dept.
qorkfiend writes "Optware Corp. has announced successful playback of digital movies on a new holographic recording disc with a reflective layer. Known as the Collinear Holographic Data Storage System, the disc has a one terabyte storage capacity and one gigabyte transfer speed. The disc size is 12cm, comparable to that of a DVD and a CD."

      A DVD has 4.7Gb right? But people trade quality for size, and rip it to 700Mb files. How about Telesync?

      There's FLAC, but a lot of people just use 128kbps Mp3.

      Big file format IS NOT a solution to piracy.

      • No, but it is a solution to increasing the value of the product. And value is the reason people buy things.

        I mean, there are lots of people who buy DVDs of content freely available on the internet. Atom films and many of the Flash animation sites generate healthy profit from DVD sales and I'm surely gonna buy that Strong Bad's 100th Email DVD when it comes out, even though I have all 111 flash files on a DVD already...

        Why? Because the quality is better and the format is more attractive and convenient. Making the assumption that it is going to be rather difficult to stop piracy, one way for the industry to encourage people to buy films is to create formats that have even HIGHER quality with even MORE convenience and to release them SOONER in even nicer packages.

        DVD is a first good step towards that goal...tape sales used to be sort of an afterthought, just another use for movies that were intended to make money during their theatre run. Now, DVD sales might bring in a substantial percentage of a film's take, and some media (especially TV series and indie films) make MORE money on DVD then they did first run. As a result, the industry is releasing movies earlier and with more extras than you'll find in a 700 meg XVid file.

        There will always be people who are satisfied with shite quality willing to pirate. The goal of the industry should be to fight the pirates the only way they can (through lawsuits) while simultaneously making it easier and more worthwhile for people not to become pirates in the first damned place.

          But one thing I have to ask is, will this format actually look higher quality on a normal TV? Cause if it doesn't no-one will upgrade till HDTV or whatever becomes far more commonplace.

          Hell, the average person cannot tell the difference on a TV of a DVDShrink transcoded disc to 47% quality and an original DVD disc. It's a limitation of the standard TV's. On a computer screen it looks like crap, but on TV looks the same.

          My point then is that, this may be 1000 times better quality, but if you need the next resolution leap past 1080p to see it, quality will not sell the players and discs.

          And convienience won't either. DVD's were a major step up from VHS. Noticable quality, sound, no reqwinding or wearing out/strectching of the tape, smaller, easier seeking/skipping etc.

          But what do these have over DVD? They are the same size, and presumably will have the same navigation abilities. The quality improvement won't be noticable on the next generation system of audio and video, much less what is in homes now, and for at least 5 yrs to come I would guess. So what makes these attractive?

          All 3 LOTR extended edition movies and appendicies on one disc? Ok there that is a draw, but really - how many movies are just - hollywood homocide - not epic, not a trilogy, no real interesting advances to make it... So no big extras. So what is the draw?

        Huh? [vcdquality.com]

        I'd say it's more like this: What format is used for piracy is directly related to how common the media is on the market. CD's are probably still more commonly used than DVD's, but one can't say that DVD hasn't became much more common only the last few years without lying.

        I've also seen some Telesync rips [vcdreview.com] being more and more commonly as DVDR to minimize quality loss.

      It's pretty safe to assume they mean per second. A CD drive has a baseline speed of 150 kb/s. That means that a 48 speed drive has a transfer rate of 7,200 kb/s. Now if we increase the data density to 1 terrabyte, we find that we are now capable of reading 11 gigabytes at the same RPM. Given the greater complexity of this technology, they've probably reduced the RPMs to something more along the lines of an 8 speed drive. This would reduce the data transfer rate, but impose fewer stresses on the media.

        How do you arrive at 11Gb/s? Looks like (7.2Mb/s / 0.64 Gb * 1Tb) - That would be wrong. The areal density increases about 1560-fold (assuming 640Mb/CD), but the linear density increases only by the square root of this. The amount of data that passes by the reading laser along the track would be just 40 times larger for the holographic media compared to a CD at constant RPM, which would result in 'only' 288Mb/s. With 1Gb/s, they'd still be a factor of 4 away, but that's still closer than your estimate.

          You're assuming that the number of tracks increases at the same rate the linear density increases. That might be a reasonable assumption for DVDs vs. CDs, which are made denser by scaling everything down (which you can do because the light is a smaller wavelength and can resolve smaller features on the disc), but not so much for this format.

    However, the low-end/consumer-level backup market is mostly using CDs and DVDs these days (due to the cost associated w/ tapes/drives). I see that market segment moving to this more or less instantly, while growing at a VERY rapid pace (similarly to what happened with Zip disks/drives about a decade ago).

    (And yes, I am assuming that this won't hit the market for a few years - however, given that the biggest standard drives are about 250GB now - and uncommon - it seems unlikely that drives will commonly be much larger than 2 TB 4 or 5 years out, such that HVD would be an inconvenient backup solution (compare the inconvenience of backing up a 40GB drive -> 10 DVDs, vs. a 4 TVB drive -> 4 HVDs).

    The above presumes that they can get the tech out there for a market appropriate price - while the article doesn't shed much light on pricing, I can't imagine that new HVD media would cost too much (prob. a similar prive curve to DVD). However, the price-friendliness of the servo-technology they describe is pretty much an unproven quantiy, so who know how much the players/burners will go for...

    Whether the media companies follow-suit and use the media to distribute movies (i.e. create compatible players), I have no idea. However, people will lilely be backing those movies up on these HVDs, even if only to re-burn to MPAA-approved-media-of-the-week later, as I don't see digital distribution of (uncompressed, un-DRM-encumbered) digital HD coming down the pike anytime soon.
