An Australian researcher has worked out how to store 1000TB on a CD

Well this is interesting, it actually is lol ;) (PS I actually searched the forum and found nothing on this, I know its an old story)

So we all know data is an issue, we are producing a huge amount of it (although I did not know that 90% of all data we have stored was produced in the last 2 years which is very surprising but any way) and eventually we are going to have issues storing it. Well looks like optical media might be the way forward… surprisingly

A researcher in Australia, Dr Zongsong Gan, has managed to write 1000TB onto a DVD back in 2013 (not sure why the article headline says CD). I am only seeing this now because he just won a fellowship.

 

Ok so how it works is actually pretty ingenious. So up until this research was made public it was believed that there was a physical barrier known as the diffraction limit of light which meant that light cannot be split any smaller than around 500 nanometres and because of this it was thought that light wasn't capable of writing bits of information smaller than 500 nanometres across. And while you may start to think that Gan somehow broke that broke that physics barrier he did not, the world has not changed :P Gan used 2 different coloured lights (red to write and purple as an excluder) to restrict the area that could be written down to 9 nanometres across, extremely impressive tbh.

The two main reasons the story is cropping back up is because of the fellowship but also because seems that this team will start working with other researchers and industry to start using this new discovery in more practical ways

It seems optical drives are still going to be a thing for very long time and most case makers didn't see this coming lol.

external FTW, put them in a drawer when you don't need them.

The thing with those are I always want the sexy awesome one, then I realise spending like 100-200 on a CD drive is ridiculous then never ending up getting one

Shame qwerty, you never read my post  :angry: ....  :P

 

IF ;) you had of read my OP you'd see I mentioned that, the fact that it was not a new story and the fact that I have no idea why they talked about a CD when it was done on a DVD. Ignorance, laziness or sensationalist on the part of the writers no idea.

 

Regardless it is a cool story that I could not find on the forum :)

and see how this compares

This is neither a CD nor a DVD... it's an entirely new Optical Disc format.

CD, DVD, Blu Ray etc are as much about the type of Laser system used as they are about the form of the physical disc itself.

I really thought this would have been on LTT a while ago given the group pulled this off more than a year ago.
