6 Firms Form Holographic Versatile Disc Alliance

gardolas writes "'Fuji Photo and CMC Magnentics are two of six companies, who have formed a consortium to promote HVD technology, which they say can be used to put 1TB of data onto just one disc. The consortium say that a HVD disc could hold about 200 standard DVD's, and transfer data at speeds 40 times that of DVD, about 1GB per second.' HVD is being seen as a possible successor to Blu-ray and HD-DVD technologies."

Re:Hard disk bottleneck

[tomstdenis]

Well "technically" PC3200 means 3.2GB/sec. But yeah, in practice you only get [anywhere near that] that doing series of uninterrupted perfectly timed 8-byte writes to sequential memory...

1/10th of a LoC

The LoC is normally quoted at 10tb [techtarget.com].

Re:Hard disk bottleneck

[Anonymous Coward]

No, modern RAM has 6+GB/s of theoretical bandwidth, and even in real life conditions can usually handle significantly more than 1GB/sec.

Of course getting the data to the RAM might be a different story, SATA, SCSI, and even FiberChannel are all =360MB/sec these days.

But by the time we have HVDs that fast, I'm sure drive connection busses will have improved considerably.

Acronym confusion

[mike5904]

Technically, the article stated that the transfer rates would be up to one gigabit per second, not 1 GB per second, as the summary states. That's certainly fast, but not beyond the capabilities of current hard disk/memory technology.

That's how it works (Re:Holograph? )

[helioquake]

I heard about this new technology a few years ago. I didn't realize it is about to be commercialized...

Anyway, the parent poster's example on Star Wars has it right. Basically the projected holograph at a different angle (or viewed at different angle) shows a different holographic pattern (i.e., from the front, you can see the princess's face. But from behind, her arse).

The different angle of the incident beam generates a different look of interference map, which in turn translated to bits. It doesn't seem too far off that you can hold "Library of Congress" in a tiny data cube between your finger tips...

PS. Do I want it? Sure. I have 1TB data of my own at work. It'd be nice to back them all up at once.

Neither can these ...

[AlgoRhythm]

according to TFA:

The consortium said an HVD disc could hold as much data as 200 standard DVDs and transfer data at over 1 gigabit per second, or 40 times faster than a DVD.

Might be worth mentioning...

[ibringthelight]

From the slashdot article:
"about 1GB per second"

From the cnet article:
"transfer data at over 1 gigabit per second"

Slight difference there of about eight times...

Who on earth needs a terabyte of storage?

I do computational fluid dynamics -- it is quite easy to generate a terabyte of data in a week. A typical 3-d simulation may be 10 terabytes (including restart files). You usually want to keep the whole dataset around for a while so you can analyse it, and probably need it to be easily accessable until you finish writing the paper(s) describing it (which could be 6 months or so).

So, I could fill up several of these right now. All my data is stored on mass storage systems at various supercomputing centers, but it would be nice to have a local copy too. And RAID is not a backup -- I would like a true backup that I could place in a place physically different than my computer.

If the boys and girls at Redmond keep expanding the windows kernel at it's current rate we'll need all of that 1TB and more!

There's a cool article here [extremetech.com] for those interested in a little windoze history.

Successor to Blu-ray and HD-DVD technologies

[CastrTroy]

Does it bother anyone else that they are talking to successors of products that aren't even out yet? I mean, if blu-ray doesn't hold enough data, then we've got a problem. Because with the existence of DVD's they've proven that even though the technology is there, the publishers don't want to put more than 1 movie, or 1 album on a single disc. If they did, I'd be able to go out and buy the a DVD with the complete TU-Pac library. The only problem with this is what happens when he comes out with something new. Then I have to buy another disc.

MPAA, RIAA, Microsoft... the Anti-Christs.

The consortium say that a HVD disc could hold about 200 standard DVD's

Of course, those idiots at the MPAA, RIAA, Microsoft, and other left-wing anti-freedom organizations will find ways to make one movie take up a whole disc...

For example, they'll decide that instead of burdening the DVD player with both decompression and unencryption, why not make up an encryption algorithm that is a thousand times as difficult to crack, while placing the movie on the disc uncompressed.

They'll advertise this as providing even higher quality than DVD, which it will when viewing takes place, and they'll sell it to so-called "content providers" as preventing piracy, which it will not do.

Their ulterior motive, as we all know, is to get Congress behind them to allegedly "prevent piracy" when what they actually want to do is prevent Linux software from being capable of playing videos and music. Microsoft wants this because it gains additional power, such as the ability to push its Media Center version of Windows XP without unwanted competition from Linux vendors. The price can be high, the software can be so buggy that it might work, maybe, once in a while, sometimes. But users will pay this price and live with the unreliability and inefficiency of Microsoft's product because they will not know of any alternative (read: Linux) which can do a better job, cheaper, faster, with less hardware, and with higher customer satisfaction.

That is but the short-term goal. The long-term goal of these terrible organizations is to chisel away at our freedoms so they can control our lives and turn the free countries of the world into something that makes the former USSR look like heaven.

right-wing would be more appropriate, as the 'right' stands for 'conservative,' people who want things to stay as they are

I've got news for you. Your statement is what the left wants you to believe that the right is.

Start researching, reading, and taking the time to understand what the right is all about, and you might discover that it's a whole heck of a lot nicer, kinder, and friendlier, not to mention fairer, than the left would have you believe. Unfortunately, people get so used to hearing certain things in the media (which is controlled largely by the left) and in schools (also left) that they have a certain model of the world that says that businesses are evil, etc. Unfortunately, most business owners, who are honest people and who create jobs and really do make a genuine effort to improve the lives of their employees, are adversely affected by the above sentiment and by the legislation that results because of it. For example, higher taxes, increased regulations, and other burdens placed on employers really make their life unnecessarily harder, as if running a business isn't hard enough, and ultimately destroys jobs, causes business failures, unnecessary litigation, and other problems.

The cause? Politics. The left really has nothing to offer. It is misguided. Just look at all the anti-God stuff that was going on before the 2004 election... And a month or two after the election, suddenly the Democratic party, which is mostly left, announces that it is very pro-religion. Why? When months before it was decidedly anti-religion? Because that's the message they think you want to hear... so that's the face (the mask, essentially) that they put on, in order to get your vote, to get into power, so they can do what pleases them.
