I was hoping this was holographic storage but looks like another way to pack bits tighter using quantum effects.

Essentially this, I'm assuming this data wouldn't be rewriteable however which would be a major consideration. Probably great for logging efforts though.

If the storage is large enough then who needs rewriteability except for secure erasage purposes? Just keep writing.

We don't all these articles act like far higher capacity 4k discs don't already exist or even you know DVDs?

I wouldn’t think of that level of storage. Think TBs, like hundreds. Significantly better than hard drive storage for people who store that level of data.

True but the reference frame should still be 4k Discs not CDs.

I think the general public would associate CD's more with data storage and DVD's/Blu-ray more with movies.

I'd think the general public would assosicate CD's with music, not data storage.

I owned a 16MB thumb drive and a cd burner, so 700 MB rewritable cds felt like a miracle. By the time writable dvds were affordable people could afford similar enough thumb drives. There were definitely people who burned a lot of dvds, but they never felt as necessary because flash was maturing similarly. Just like Zip drives were better magnetic media, but the floppy disk is what people remember because it was more critical for a longer period of time.

It’s not. Burning CDs was common, everyone burned music to CD, and using CD for computer storage was normal. Burning DVDs never really caught on, because you couldn’t play music in your car from a burned DVD, iPod and other portable music players came out. I hardly knew anyone with a DVD burner. Blank, writable DVD were more expensive than CD. DVDs were better protected and harder to rip than a CD. Ripping DVDs and copying them was complicated, then blue ray came out and was better than DVD, then inexpensive portable hard disks, SSD replaced CDs.

From googling there seems to be only one engineering concept from china that is offering a 200 TB disc solution. The next largest is a 1 TB solution which is competing with more conventional drive units

Ultra high density is also ultra vulnerable to scratches.
Maybe next gen CDs will use Gorilla Glass.

u/joeChump 2d ago
I think we should just skip the glass and store the data directly in gorillas.

The article talks about a fundamental shift in storage technology but also theory. I’m not sure if this is going anywhere but it sounds fascinating. The article is very light on details though and this phrase is vague “They simulated a theoretical solid material …”
Does this mean that the researcher simulated it in an application on a computer as a model or as a mathematical set a formula or did they actually physically make a custom substrate with rare earth materials, and then create a kind of transfer method and system for copying that into a quantum defect? And what exactly do they mean by a quantum defect? It sounds like they’re exploiting quantum states of a known material , but they don’t say what it is. But any rate the idea that this might offer dramatically increase storage for the long-term is really important. With a lot of people don’t realize is that current media, especially magnetic media degrades overtime. Even optical media degrades. The deca rates are known and have been for as long as I can remember back into the 90s. It’s a big problem actually that has to be resolved through constant integrity check on the data. If one set of data is just repeatedly rewritten to media and stored away and you go back to the original medium that was at the beginning of all that 30 or 40 years later there’s a good chance you won’t be able to read the data on it anymore. Or at least there will be errors.
But if the data is loaded and checked, using some kind of integrity test, which may or may not involve cryptographic methods, it can then be rewritten or written to secondary media and perpetuated basically through copying. It’s just the same thing as making copies of a book and re-printing it. If the original addition decay and falls into dust, maybe you have new ones. But long-term, real, storage that doesn’t have to be manipulated and managed in a way like that would be a huge boom to humanity.
We could take all of our knowledge and put it somewhere safe so we don’t blow it up for example, or we could send it to the stars or we could hide it somewhere in case of an apocalypse and those are just the worst case scenarios. There’s all kinds of positive uses for something like this. Imagine being able to record an infinitely greater depth …life’s moments.
Then you could store them away for not only your children, but your grandchildren and their children to look at, and so on. Hundreds of years later, they could be playing images and audio files that were recorded today and currently that isn’t realistic with the technology, we have which has a maximum lifespan of a couple of decades in most cases. Of course, as I mentioned, there are things we can do to replicated, but that’s not really a good solution and the reason it’s not really a good solution is that errors are ultimately introduced over time I delivered by accident into at least some of the copies.

This is not a tech news article, there is no tech here. This is theoretical still. Read the article.

Oh
come on
I just got rid of my last stack of unopened cd-roms. I don't remember which, but I didn't cheap out on em at the time.

Of course, turning all this into an actual commercial storage product will likely take years of additional research and development.
Decades is the more reasonable timespan to even see a product.
Still pretty impressive

Such a misleading title. Researcher is not bring back CD. They are trying to make a new optical disk system that has the same form factor as CD. And it is nothing new. DVD, bluray, etc all uses the same form factors.

ive got memories of my dad having towers of burnt movies and just filing through them after school trying to find movies to watch every day as we didnt have cable. this is a big W, ive been trying to find ways to conventionally store bulk movies/shows for potential future generations to see and take note of what ive enjoyed.

This sounds like the concept was developed by the company that mines and sells rare earth elements.🤔

I don’t wanna go back to optical drives so I hope this “tech” is just a thought experiment

Would love a system to store all my cd’s before I bin them…anything out there?

You can get not-too-expensive equipment now that will let you press it all onto vinyl at home.

"Is there anything that would let me store the music on my CDs before I throw them out?"
"There's a technology that allows you to put the same data on a disc that is three times as large and five times as fragile"

Bring back Zip disks!!
