Bandwidth. What if I could hand you the totality of Netflix, iTunes, etc.? Not wait for it to download, but transfer large chunks of the Internet in seconds? and no longer have to hope that, say, Netflix won't lose vast sections of their library for contractual reasons (as it has done of late)? Backups: permanent archiving of everything you have all on one disc. It makes vast swaths of data yours, in your hand, under…

Netflix would put the entire catalog in your home, encrypted, and the only data they would have to transfer would be for the control plane (billing, recommendations, etc) and encryption keys to auth you. Totally side-steps last mile monopolies as well. Don't want to work with us? We'll drop an LTE chipset in as well for the admin stuff. Redbox In Your Home.

That would remove their ability to take content away from consumers when contracts expire though wouldn't it?

The encryption keys would be time limited (monthly basis, certain titles, etc). If you don't top up monthly, you key expires, the underlying data is re-encrypted with another key, etc.

Dr. Gan needs someone to introduce him to Kickstar…

I guess this is because the technology only solves one of the problems (getting a very narrow writing beam/point) and not the others, like: making the disk so stable that it doesn't wobble for more than a few nanometers during rotation; keeping the laser beam focused on the disk; figuring what kind of rotational and seek speeds (=read/write speeds) you can handle with these limitations; making everything small and ready for market.

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…

People find use for empty space.

To be fair, they don't have that ability in the first place against a determined attacker. (Ie once they show you the content, you can grab it.)

How do you re-encrypt a read only storage medium like a disk though?

Yeah that's true, but I would say the majority of people aren't ripping Netflix streams in case Netflix's content licences expire. If they are given a master disk with everything on it, anyone with that disk has the data on it in perpetuity (barring storage failure)

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…

You are forgetting that the speed at which optical drives can be written is bound by the rotation speed. If you have a single laser of this type and mount it in a traditional drive as we know, it would take over a year to write a single disk :) Still lots to do :)

The majority of that is junk anyways. But I suppose some people obsessed with archiving everything wouldn't filter anything. If I were to grab "everything" from YouTube I would at least limit it to subscriptions and only subscribe to channels that don't upload bogus junk.

Then the valuable commodity would become directories of worthwhile content. You would have people doing deep dives into the crap to find the locations of a few good pieces to share with their buddies or trade.

With the internet and Video On Demand that's already the case.
