Japanese researchers have announced that they can use a new metal oxide that will usher in a new-generation of Blu-ray Discs that are able to store up to 200 times the capacity of the Blu-ray Discs available today.
If the product is fully developed successfully, this means that we could see single layer Blu-ray Discs storing close to 5 TB (200 x 25 GB) of data in the future.
Research carried out by Japanese professor Shinichi Okoshi, who teaches at the University of Tokyo, also demonstrated that the metal oxide is cheaper and easier to manufacture than materials currently used in DVDs and Blu-ray Discs.
To put it simply, this new metal oxide is a synthetic material that coats the outside of discs. The black layer is dynamic and allows electricity to pass through in an easier manner than what’s currently offered. If implemented properly, the new discs could store 1,000 times the amount of a single DVD, a massive storage increase when compared to the 25 GB capacity available today.
Researchers plan to work with manufacturers to try and see how quickly their technology can be utilized.
The current DVD and Blu-ray alloy costs more because manufacturers are using rare metals, such as germanium and other pricey compounds. The ability to use common compounds will keep manufacturing costs down – and Okoshi is ready to work with manufacturers to accelerate the use of this new alloy.
The full published study can be found in the May 23 Nature Chemistry science journal.
We’ve seen a few different storage breakthroughs recently that promise drastic capacity increases for Blu-ray in the years to come. Although these new technologies sound extremely promising, very little actual real world prototypes have been seen as of yet. Let’s hope these technologies don’t become vaporware.
Update: As H3rB3i rightly pointed out in the comments below, this new 5 TB disc is not actually a “Blu-ray Disc” and is being referred to as a “super disc” for now. Our apologies for the mix-up.

DVD and BR disc's all I can say is bring it on and don't be slow about it.
Just curious .....
Along with new Blu-ray drives to play the discs, since I'm guessing current players will be unable to read them.
5TB

As appealing as 5tb may sound, something has to read and write to these disks and the current crop of Bluray players and writers isn't going to cut it. The tracks on these disks will have to be 200 times narrower to hold that much data. Thus the laser will have to be 200 times narrower and have to track 200 times more accurately. Your next 5tb Bluray player might well set you back 5 Grand. Don't think that's going to go over too well with the average consumer.

cosidering the time they required to get Blu-ray on the market, I think they need 10 + years
, ok, maybe they are faster but this is for sure far more work than the BD developement.the key question is, who needs such a disc. I mean SSDs are becoming more and more affordable, you can get small HDDs with lots of storage, mediastreming,.... I really don't see any use for such a disc
Just think on 1+ TB SSDs in external enclosures, who then want's a CD/BD/DVD any longer?
imo they will be affordable far before such a technology will hit the market

They must reduce the track pitch again drastically (even more than by factor 2, maybe by factor 10) to achieve the capacity they promised. Imho this is impossible with a blu laser technology.

They'll all want one.
It's a hard disk drive back in 1956... with 5 MB of storage. In September 1956 IBM launched the 305 RAMAC, the first 'SUPER' computer with a hard disk drive (HDD). The HDD weighed over a ton and stored a 'whopping' 5 MB of data.
Do you appreciate your 1 GB memory stick a little more now?

Blu-ray writers & players
- Blu-ray has won the war for the new high definition optical format. More frequently manufacturers are presenting laptops and desktops which feature a blu-ray drive. Blu-ray players are only able to read Blu-ray (and CD/DVD) media, whereas Blu-ray writers are able to write Blu-ray, CD and DVD media. At the moment blank Blu-ray drives are still rather expensive though, but Blu-ray offers high storage capacity which makes it an excellent back-up medium.More about this
