  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Here’s how to fit 1,000 terabytes on a DVD

In Nature Communications today, we, along with Richard Evans from CSIRO, show how we developed a new technique to enable the data capacity of a single DVD to increase from 4.7 gigabytes up to one petabyte (1,000 terabytes). This is equivalent of 10.6 years of compressed high-definition video or 50,000 full high-definition movies.

Who said optical media is dead? :)

But who buys DVDs anymore though?
 
Whoaaaahhhh... 6k RAW archive!
 
I wonder how much error correction will need to be built in...
 
Optical discs would be fucking awesome again if they could hold 4k lossless masters along with all the special effects and more. Imagine owning the entire works of Kubrick at 4k on a single disc? I still love the idea of physical ownership that isnt at risk of a hdd crash.

If it's really DVD's then just make 10 backups, should set you back a dollar or two.

Precisely, and then I could do away with the hundreds and hundreds of disks I have lying around that I'm too busy to preview and too leery of throwing something important away.

*SCRATCH* Awwwwww my data . . .

Scratch... Ups, there goes 500GB of data...

CD's were reasonably resistant to scratching as the width of the optical track was quite thick.
DVD's with their thinner OT were more sensitive to scratching and HD-DVD/Blu-Ray ever more so...
This new tech with 9 nm OT will be an absolute nightmare IMHO - if it ever makes it to real world production...

Scratch... aww... I have another 10 backups cause its just a DVD ;)

EDIT:

On a serious note, this tech is amazing, and it is not as if making a scratch resistant DVD is an insurmountable task. I am sure that if the worlds best minds put their heads together, they could make a decent scratch resistant DVD coating...

Wait, they have:

Never tried these,, but that's hardly a reason to dis the tech. Can't wait to have a petabyte in frisbee form.

Not in this case. DVD's can often still be read, even with significant scratching, because the data regions on the disk are typically big enough to accommodate such errors. Blu-Rays are more sensitive as they have 4X the data density. This 1 PetaByte DVD concept uses even smaller data structure sizes. A barely visible grain of dust on your disc could wreak havoc. I really don't see how this technique would be viable. Yes, it's kinda cool, but not if every disc will need to be maintained and operated in ISO 9005 clean room type environments. In order for this to work, the disc and the laser control mechanism will need to be contained within a hermetically sealed enclosure, protected away. Similar to a hard drive. And while we're on the subject of that, HDD makers are pushing now to get yet another new implementation on the market, although it may be too little, too late. HDDs are about to go out of style.

OK, so what if they developed a RAID structure on the disk whereby it had reduced capacity but multiple copies of the same file to give it better ability to avoid the speck of dust? Just wondering out loud.

Orrrrr, what if they could do the same thing to a CD (I've got a lot of those left unused '-)... or even those little half-sized disks. All I'm looking for is cheap archive!

Poor Boy's clean room? Air ionizer in a closed off room. In my mind, running one of these for a sufficient amount of time before writing or reading the disk should eliminate most of the dust potential, as the ionizer "ionizes" the dust and draws it to a collector. Besides, if a nano-scale dust particle gets onto the disk, how many 1s or zeros does it cover... and wouldn't a laser burn through it? Just askin.
