If this is real and can be commercialized it could lead to some pretty devastating fallout for the entertainment industry. You've got to know that there are a few obsessive archivists out there with pretty comprehensive collections of films spread across rooms of RAID arrays. When they can start backing those collections up for friends onto a single disc, ie a single disc that has more films than you could possibly w…

Books are small enough that this has pretty much already happened (search for "library genesis").

Library genesis is the best thing that happened to research since Google (and a huge number of researchers use it, secretly). Being able to access any obscure technical book in the world in a few seconds is literally orders of magnitude more efficient than waiting a week for an interlibrary loan. I dread the day it inevitably gets shut down due to pressure from the copyright mafia. It's ridiculous that such a service isn't 1) legal, and 2) publicly funded (with due compensation to the authors).

Could you explain more exactly what "library genesis" is? Is it a collection of basically every book ever published or only modern things? Did someone scan everything, like Google books?

> more films than you could possibly watch in your lifetime I was curious if this statement was true... So assuming, 4.4 GB her HD film & 2 hrs long each, you can fit roughly 232 films per TB or 232,000 films total (for 1000 TB), that's 464,000 hours of HD content or 53 years (!) back to back. So, yes, that statement is true. Now the next logical question: Has the human race produced 464,000 hours of video content? L…

And there are of course vastly more than a 100 cable channels. BSkyB alone broadcasts more than 600 channels for the UK market (more than a thousand if you include radio). In 2010 Ofcom passed 1000 licensed UK channels.

The US is supposedly the only other country with similarly high number of channels, but I don't think it's unreasonable to assume that there are more than 10,000 channels worldwide.

Earlier quoted context omitted.

Everything I find related to that seems to have been shut down, are you getting better luck?

gen.lib.rus.ec and bookfi.org both work for me, some time ago I investigated the origin of those collections and apparently they began as a set of 30+ dvds that have been distributed presumably primarily in russia for quite some time. Especially in math and physics they are every poor graduate students dream. Even large libraries have only one copy of some of those books stuffed away in some underground vault.

And engineering and CS, both undergrad and postgrad. Fantastic website for when the library was out of stock of that book published 40 years ago that there's only 3 copies of in the country...

> Every day, humans are producing more data than ever before - around 90% of the world’s data was generated in the past two years alone - and there will come a point when our data storage centres and the cloud can no longer keep up. Is this true? Can anyone point to a some kind of study showing convergence of storage capacity and data production over time? I was under the impression that we've got far more storage th…

Given that we can today fit tens of TB in a fistful of SD-cards (512GB per card), no I don't think it's true at all that we'd get to a point where our data storage can't hold up. Our ability to filter and identify gems outside of the most popular stuff is a far greater challenge.

Expect Amazon Glacier price to drop dramatically in a couple of years :)

Why downvoted ? Allegedly, blue-ray recordable discs are used by Amazon for Glacier backup. Surely they will be the ones very interesting of further development of this technology.

Awesome tech. I wonder how data will be written and read from such a disk? How long will it take? The transfer of 1000TB will be an interesting problem indeed. At current theoretical blu ray writing speed of 12x or 400Mbps [1] the time to read/write such a disk would be: 1000 terabytes = 8,000,000,000 megabits 8,000,000,000 / 400 = 20,000,000 seconds (7.6053 months) [1] http://www.blu-ray.com/faq/#bluray_speed

Could probably be written all at once using immersion lithography. You could threat them as big read only memory 'crystals'. Buy a set of 100 containing entire YT archive etc

The idea to break the diffraction limit by using the this doughnut-shaped excitation spot comes from the STED microscopy ( http://en.wikipedia.org/wiki/STED_microscopy ) developed by Stefan Hell (Max Planck Institute for Biophysical Chemistry in Goettingen, Germany). He actually showed that an additional intensity-dependent term can be added to Abbe's diffraction limit allowing sub 100um resolution with light. I thin…

I'm sure this or a similar technique is already in use in commercial photolithography.

I'm wondering if the entertainment industry is the reason for which Hyper-CDROM[0] is not commercially available. If so, something is very wrong with the way society incentivises development and commercialization of new technologies.
