Researchers Find Way to Put 1.6 TB on a DVD

[chovav]

"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.

The article title is mis-leading. It says 1.6tb on a dvd disk but the article actually says dvd "sized" disc which makes a big difference.

Old news, this story was on local TV news two weeks ago.

And this will be available TO YOU in twenty years for the low low price of $2000!

[citation][nom]starryman[/nom]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.[/citation]

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.

optical media is lame

im not sure why everyone is saying they get tons of coasters. i myself have only ever got 1/20 some odd to be a coaster, even with lite-on drives.

btw, other articles i have seen tells that the firm believes it can eventually store 10,000+ times standard dvd.

Not that big of a deal if you ask me. Physical media is on it's way out anyways. Especially with big companies like Apple pushing downloadable content.

Sony would come up with a competing format and ruin it. Maybe it will then find a niche as a true high-definition audio disk.

what would a small scratch on the surface do?

I'll be impressed when they can make an optical writer that can write to a 6th dimension: Time--and can be used to rewrite history! Bwahaha!

Of course, then someone could really make things interesting when they try and copy that porno onto dvd. Hmm, maybe we oughta think this one through first.

 

[misnad]

ok.. this is going to be interesting.. hdmi 1.4 coupled with this amount of storage capacity and we could have a new definition for full HD..

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.

 

[ericgunnerson]

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!!

 

[2shea]

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.

i am from australia. I know news media here are just all spin and no substance. Here ignorance is rewarded. In australia the media have it we are always break throughs from athletes to tech. We just add an variable to an equation and Wham bam.

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.

[citation][nom]zingam[/nom]I'd be satisfied with 50 gb per disk that is really reliable.[/citation]
Zing... that would be a standard dual-layered BluRay disk. They are available today (blank disk) for about $2. The player is about $100 and a burner is about $300.
