Researchers Find Way to Put 1.6 TB on a DVD

By - Source: Tom's Hardware US | B 43 comments

1.6 Terabytes on a single disc.

With hard drives hitting 2 TB, our dual-layer DVD burners are starting to look mighty limited. While Blu-ray Disc burners will be making their way into high-end computers soon, it won’t be long until even 50 GB seems puny.

Researchers from Melbourne's Swinburne University of Technology claims to have developed an optical recording technique that it says can place a theoretical 1.6 TB on a DVD-sized disc. This is done by adding extra dimensions to the recording surface.

To be precise, the extra dimensions are the wavelength and polarization of light, which integrate with the familiar three spatial dimensions creates true five-dimensional recording within one volume.

According to the journal article from Nature, “The new system makes use of surface plasmon resonance (SPR)-mediated photothermal reshaping of a substrate of gold nanorods immersed in a polymer layer. Crosstalk-free readout is via two-photon luminescence. Immediate applications can be found in security patterning and multiplexed optical storage.”

According to a BBC report, the Australian research team is now working with Samsung to develop a drive that can both read and write using the new method.

“The optical system to record and read 5-D is very similar to the current DVD system,” says James Chon, a co-author on the research. “Therefore, industrial scale production of the compact system is possible.”

All-new equipment is needed to manufacture discs on the new format, which is a barrier for the technology’s adoption. The researchers cite the eventual industry investment into the switch Blu-ray Disc as an example of how their technology could someday be crowned the next optical format.

    1.6 TB on a DVD disc...wow!
    Somebody did a marvelous job.I wonder how the industry would respond to this and how this technology is going to evolve.looking forward!

    That was a 20 layer one. Anyway, I think this technology is very...unstable. What I mean is, there could be frequent read/write errors.

    I have heard about multi-layer miracle discs at least 10 or more times over the years. They never come to pass. I remember Constellation 3d back in 2001. They had supposedly perfected fluorescent multi-layer writing and could do 5gb per layer. They were working on 100 layer discs (500GB per). The company was run by thieves who milked its treasury and took the investors for a ride. Take this one with a grain of salt. New battery technologies are also infamously fallible.

    And yet my DVD burners (LiteOn, Pioneer, Samsung, LG) continue to make more coasters than I have cups. I'll believe this when they can at least make the current DVD burners more reliable.

    i bet its not even reliable... like most discoveries .... 3-4-5+ layers.... im sure there is a lots of errors and 1 scratch... and its over...

    Article title misleadingly insinuates current DVD disc and recorders can be used.

    more like... someone solved an equation. note that it says "theoretical"

    whoa 5-D???

    I thought 4-D was like getting into time travel or something

    Conceptually similar to Fluorescent Multilayer Disc (FMD).

    I think products for it exists, but not for the consumer. Conspiracy theories, anyone?

    It sounds promising, but they did say it was theoretical which means nothing unless they have a working prototype. I would be willing to buy this new technology but it better be rewritable as I can't possibly write 1.6 TB on a single go or they can implement a unclosed means of writing to the format like Roxio does for "-R" medias (possibly others but I don't know). Another issue is speed... Is 5 minutes per 1.6 TB asking to much... Alright 30 minutes max for 1.6 TB, no exceptions.

    I'd settle for those damn dual layer DVD's hitting anywhere near a reasonable price. Everyone and their grandma has a dual layer burner, but the discs are pure extortion. Now we have Blu-Ray and other technologies hitting the market that are supposedly harder to manufacture. How can we afford to burn even one coaster on these things?

    I'd but the B-ray version. :p  I dont even have a B-ray drive yet.

    It's a pretty smart idea. just like how packets are compressed and digitalized.

    maybe we can now get a Gb from 5 1/2" floppies. HD Beta tapes. Think of the possibilities.

    i'm not excited because all the other surrounding technologies are lagging way too far behind to make use of this optical storage space. look at how blu-ray is failing because it is too far ahead of its time.

    why just use the B-ray diodes the 5-D recording and the holographic disks and put them all in to one giant overpriced priced package, and have disks that can hold 20 Exabites. you keep hearing about new recording techs but they all hold around the same amount of data and will need new player. i will never be able to bring my self to buy any of them and ill be stuck with my DVD drive.
