Half a terabyte on an optical disc

Postby gmalivuk » Tue Apr 28, 2009 4:22 am UTC

A disc that can store 500 gigabytes (GB) of data, equivalent to 100 DVDs, has been unveiled by General Electric.

The micro-holographic disc, which is the same size as existing DVD discs, is aimed at the archive industry.

But the company believes it can eventually be used in the consumer market place and home players.

Blu-ray discs, which are used to store high definition movies and games, can currently hold between 25GB and 50GB.

Micro-holographic discs can store more data than DVDs or Blu-ray because they store information on the disc in three dimensions, rather than just pits on the surface of the disc

Lovely, but how long will they last before oxidation and/or other manner of decay sets in? It doesn't matter much for many applications, but it sure as hell matters for archivists (the stated target market for this product).

A friend of mine is old enough now that he's been able to judge the relative archival merits of various media. The winner so far is reel-to-reel tape, apparently. There are tapes around that are many decades old and which can still be played. For home use, TDK cassette tapes are the long-distance runners -- said friend has 40-year-old tapes that still play fine. Maxell cassettes, at least ones made in the '70s and '80s, are mostly unusable now. CDs are ass, often breaking down within a decade or two. Vinyl doesn't degrade much if you don't play it. :wink:

(Context: my friend is a musician who has decades of his own stuff recorded, plus that of his friends. There's sometimes only one or two copies of something kicking around. If they crap out, it's gone forever.)

What do they mean by 3 dimensional storage? Are there multiple layers of data or is it some crazy hologram thing?

Also can I use it as a phaser to kill Klingons?

You may have missed the X number of times it repeated the word hologram and variations thereof.

What really excites me about holographic storage is the fact that you don't lose much if any data from a scratch that can't be read through. You may need special equipment, but you can read it from a different angle.

I don't know about longevity, but since holograms are (I believe) part of the material and therefore don't depend on a reflective backing, I can see these lasting a very long time so long as they're protected from torsion, compression, and other physical stresses, which is fairly easy to do.

This is all based on a loose understanding of holographic storage from a Scientific American that's probably close to a decade old by now, so this whole thing could be wrong.

wasn't there a story about something like this a year or so ago where they had a 10 TB prototype disc and were looking at 100TB for the next step?

Since they say this is intended for archiving, the answers are probably "no" and "not very fast, relatively speaking".

Oooooh, that was low! I love it ;D.

And I feel stupid when I can't even appreciate the importance of a storage device for half a terabyte.

Dude, I can buy half TB hard drives for so cheap I may as well use the platters for coasters.

This is obviously meant for different applications, is all I'm saying.

You still have a trade-off between density/capacity and reliability, of course. The more data you pack into the hologram, the more susceptible it will be to material degradation. But the holographic storage would indeed increase the capacity you can get for the same amount of reliability on a traditional medium.

Because the easiest way to read the data currently is to spin it. Hence the disc. Data cubes may work for solid state media such as sd-cards. But laser read will probably always be circular (or spherical! :D ).
It's all physics and stamp collecting.
It's not a particle or a wave. It's just an exchange.

What they were describing in the article isn't that much different than existing blu ray technology. A write-once blu ray has an expected life of 100 years (they store data a bit differently than CDs/DVDs). By stacking layers, they can reach pretty high storage density, as well. A single layer blu ray can only store 25 GB, but they can get up to 10 layers, which stores 250 GB on one disc (that's what currently exists, I don't know what the potiental maximum is).

I mean, you're not going to have anything even remotely like it inside your computer in the next 10 years. It's not coming. It's been perpetual vapourware, and by the time these guys actually get a working and practical product, storage will have already moved on.

Er, what? 10 years of talking about something that hasn't yet arrived makes it impossible? How long were we going on about spaceflight, or airplanes, or televisions before they actually happened? You could do this sort of argument to anything that takes a goodly time to appear.

10 years of hearing about something indicates it's not news. "Still no holographic media in your PC, film at 11, along with the lack of proof that aliens exist, and yes, Dick Cheney still a creepy guy, film at 11. That's your 2 oclock news, where we tell you about everything that isn't happening or has been happening for a rather long time!"

Reminds me of:
I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. No single space project...will be more exciting, or more impressive to mankind, or more important...and none will be so difficult or expensive to accomplish...
— President John F. Kennedy, Special Joint Session of Congress, 25 May 1961. At the time the US manned space program had about 15 minutes of actual time logged.

If people are interested in the development, it is news. Sure, this isn't landing them on the moon 8 years after a prediction, but people still care about whats going on here.

Thank you. Huge optical discs, insanely fast processors, nonvolatile RAM that can replace existing RAM, and all these other technologies are "discovered" or "created" every damn year, with the article saying they'll be on the consumer market within a year/couple months. And it never happens. In the best cases the technology is produced but the price never drops below $10,000.

Let me know when I can walk down to Future Shop and buy one of these things for my computer. Or maybe fly down there in my flying car. :roll:

Just a question: How much is too much? What purpose could you possibly use this for on the general market? Even backing up a harddrive, it's safer to use another hard disk/portable harddrive. I know that programs keep getting bigger and bigger, but who's going to take the time to program an application of 100GB or more?

I assume that my above statement will be rather silly in 1-2 decades, as people were probably saying that same thing when the 512MB hard drives came out and programs were still in the single digit megabytes. Now look at them, you can't put most games completely on them.

I'll say that we've advanced far enough when I have the internet sitting on a device the size of a Kindle, with live updating. As in, the entire internet is stored on the device, and when it gets in range of a network, it updates new pages. It also is solar powered, flexible, and shiny.
