Didn't one of the major manufacturers already announce a 6-layer BD disc a while ago? Seems like old news!

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.

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?

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.

yamThis 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.

bbcThe team members described what they did as adding three "dimensions" to the two spatial dimensions that DVD and CD discs already have.
They say they were able to introduce a spectral - or colour - dimension and a polarisation dimension, as well as recording information in 10 layers of the nano-rod films, adding a third spatial dimension.

Is it possible mr. Yam to, eventually, get your act together (leaving m$ propaganda parroting aside) and report more accurately?

Funny marketing droid language from a scientists team:
"adding extra dimensions to the recording surface", "true five-dimensional recording", etc.

Traditional CD/DVD storage uses a single dimensional encoding , the parameter being pit/land length (see EFM/+). Multiple layers don't count as another dimension for encoding, just as an extension of space for the traditional one, being asynchronous, and usually accessed sequentially, not simultaneously.
So, the virtual encoding space could be, at most, theoretically extended (with polarization angle and wavelength considered) to a 3D one, considering each one being orthogonal to the other ones.
For example, WDM is already used to extend BW, squeezing more (independent) channels on one optical fiber.
But, it would be really hard to synchronize the streams, for the different discrete wavelengths, using several lasers and detectors, on different drive units (mechanics aren't sufficiently precise and reproductible), to consider them another coding space dimension. There would be just the "classic" dimension space extension, by sequentially tuning one laser to different wavelengths, similar to multiple layers usage (optical focusing on different layers). That would eliminate another "dimension".
Polarization angle could be supposedly much easier included in coding space, but as the current research is using just 2 states (this means just one supplementary bit), which hardly could be considered another "dimension". Most probably, the laser beam is polarized one way or another, for successive passes, offering just another "layer" for storage for the "classical" one dimension coding space.
All in all, we could consider the technology as an address extension (like in a MMU) - in which the current storage spiral can be selected by layer depth (current technology), wavelength, and polarization - to the effect of a much larger storage (single-dimensional) space, as it would be seen by the user.

consumers won't need another optical tech for data. i see no purpose in these devices except for high-res and low compressed movies.
of course, companies can benefit in such for archiving data.

"surface plasmon resonance (SPR)-mediated photothermal reshaping of a substrate of gold nanorods immersed in a polymer layer"

.... which means, basically, first reshaping the surface of the gold nanorods in the disk through heat, and then reading it using the different reflection angle of the laser, which happens due to the different diffraction number of the surface (thinner/thicker), caused by its thermal shaping. Not much different from normal DVD reading method, just the fact that there are electrons being resonated in the gold nanorods.

I'm just wondering if being able to read/write 5 different dimensions on a disk is not going to end up costing a us an arm and leg.

You may have already done this...but just for anyone else who doesn't know: Drop the write speed to ~1/4 of the max and many times the problems go away.

The results also depend on the application. With audio CDs you can write discs all day at full speed (with a ton of write errors) and only suffer a few audible artifacts. Doing the same thing to a data mode disc will quickly make the files on the disc useless.

Wow what a bunch of idiotic comments...

To the haters calling BS: what they're describing is perfectly reasonable if you have even a basic understanding of how optical media works. There are pits and rises that count as 1s and 0s. That's how it works now. The additional 'dimensions' are wavelength (which is essentially color, so it would be either a blue beam of X mhz, or X+1 mhz to be 1 or 0) and polarity (which if *I* understand correctly, is whether the beam of light is coming at the lens like this (-) or this (|).

If you think that doesn't add extra dimensions and therefore orders of magnitude more space, then you are a moron.

To those who claim that they should do it with blu-ray, who says that's not what they're planning?? The article says 'dvd-sized'.

To those of you saying "what if there is a scratch", well what do you expect? the more media you cram in a small space the bigger the harm in scratching part of it. Probably they need to add a thicker layer of protection that you can polish off.

Oh and i forgot: to those of you talking about how it better be rewritable because you won't have 1tb of data to write in one shot, they're not talking about dvds you can burn at home, I'm pretty sure we're talking something that gets pressed professionally.

Additionally, to those of you talking about how nobody ever uses that space so an optical disc with 1.x tb is stupid, are you retarded? Are you honestly trying to argue that because drive space is currently ahead of usage, we should just give up on that until we start needing it again?

The more space we get, and the more processing power we get, the more we'll USE it. Nothing stays the same. Evar!!

not even fairly usefull if the speed of which it can read is as low as dvd is now :(  1,6 TB would take forever. It could be usefull in systems as cctv camcorders and such. Consumers would not need this yet. And besides that it is a theory, not something that is possible yet.

Optical disks for storage are dead.

What would the point of these things be?

You would spend 5 hours burning a disk, just to have it get scratched 5 hours later. No thanks, solid state storage for me all the way.

Have been dissapointed by optical storage for years as a means of data archiving, Tape Backup is still prevalent in Enterprise solutions, and NAS Backups are now moving in to place along with Virtualization which has been made possible with the Cheap large sized HDD's we now have access to.

HDD will still for the forseeable future be the best way of long term storage of Data for the PC user, and with the ability to use a universal serial bus, we can transprot that data around with us to other pc's on a device that fits on our key rings or in our pockets.

To use one of the these supposed 1.6tb disks yuo would be locked to your PC if no-one else has a reader, and if BD disks were to be the next best thing, i dont see other than retail movies, how they are justified at price of a disk for archiving use as it is cheaper to buy another HDD per Gb than BD disks, and far more reliable.
