Japanese Researchers Discover Way To Squeeze 42 GB Onto A DVD
A team of Japanese researchers have discovered a way to store 42 GB of data on one disc. Well, at least that’s what they claim.
When DVDs first came onto the scene, able to store roughly six times the amount of data that a CD could, it seemed like a pretty cool discovery. CDs and DVDs both have pits (really slight impressions) on the surface of the disc. The pits on DVDs are smaller and aside from that, the space between the pits, the track-spacing, is a lot tighter. DVDs can also have up to 4 layers of information, with 2 layers on either side. All of this means that DVDs can store more a lot data than CDs.
Now a team of researchers at the Tohoku University have discovered a new way of storing the data on a DVD, which enables us to store what amounts to nearly nine discs of data on just one. They say a V-shaped pit can hold as much data as 2^9 flat pits, which means there’s the potential for a disc that can store up to 42 GB of data.
According to CrunchGear the format has two major drawbacks. First of all, the researchers say it cannot be applied to Blu-ray discs, also, the discs are not compatible with regular DVD drives. Given these factors, it’s likely they won’t ever see maintstream production.

Great. So now if a disk gets scratched or the dye breaks down, I lose 42GB of data.
*cough* back up *cough*
Go back to floppies if you don't like greater capacity storage media
why the hell are you saying that having greater copasity discs are bad, this is where the wrold of tech is going, if you want to head the stone age way then please do. lol
the same with the article writer, if they managed to make these discs then who will stop them making compatible drives????
omar
Nothing "stops" them making compatible drives. But given that the tech cannot be applied to the current "cream of the crop" blu-ray media, and given that blu-ray is now at mainstream pricing levels, the design, implementation, marketing, manufacturing, shipping etc etc of a new style DVD (yes DVD) medium, that is LOWER capacity than blu-ray, is pointless.
Yes, its a great acheivement, but no, its not going to go mainstream. The article author was spot on.
"more a lot data"
