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 :)
is anyone else really bothered that the article says CD but it's actually about DVD?

I think CDs would make a comeback if you're talking about being able to hold an entire series of movies all in 4K and in 3D and not break a sweat. Digital downloads is all the rage right now, but people will still want to archive their downloads.
> people will still want to archive their downloads I don't know how true this is. Even the tech-savvy folks I know rely primarily on Netflix/Spotify/etc, and in the rare instances they buy something, they trust iTunes/Amazon/etc to hold it for them. (I continue to think that is nuts.)
I dunno, I think people allow Amazon to hold their movies for them because there's no other choice. Amazon doesn't give you avi files :(

Will this really be a larger "problem" for the entertainment industry than online file sharing? Is there many people out there that would want such a disc that already doesn't have fast speed Internet and can download any movie they want within minutes?

Books are small enough that this has pretty much already happened (search for "library genesis").
Holy shit... Just tried some obscure stuff I'd been trying to find for ages. This is amazing

> 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…

>> Let's assume there are around 100 cable channels showing content in HD video 24/7
Note that this is comparing HD content to films, though I still think you are fine in saying we easily have enough content. :)

I doubt it. There's a long, long way from the theoretical finding to the practical device.
Writing and reading speed has been mentioned. Another point is that as the dots become smaller, the mechanical parts need to be much more precise, moving the device from consumer parts to really expensive parts and assembly.

People bitch constantly, but a typical feature film encoded by YIFY at 720p will clock in at somewhere between 650-900 megs, leaning towards the lower end of that range.
Not that it matters, the rest of your math makes it look ridiculous. Without too many tradeoffs, you could certainly put every American (Hollywood and indie both) film on such a disc.
> Now the next logical question: Has the human race produced 464,000 hours of video content?
Somewhere Google has a gauge that shows how many hours of videos they store... but I can't find it.
> So even if we just look at 24/7 news and shopping channels which always produce original content, you're still talking about easily 200,000+ hours/year.
Agreed. But I don't think that they have archival policies in place where everything is kept permanently. Even the news channels may have been in the habit of dumping everything but stuff deemed important, well into the 1990s.

I'm using Plex to store our videos... sold our DVDs on craigslist a few months ago. Within 3 weeks, had another copy of every disc we got rid of.
Eventually I want to get a FreeNAS machine up and running, and any important files will be backed up to Google Drive (though, obviously not movies that can simply be downloaded again if desired).

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.
How do you re-encrypt a read only storage medium like a disk though?
You could have a master-key (or set of master keys) on a read-write medium, which you could encrypt/decrypt as many times as needed? You'd be vulnerable to someone scraping the master key from memory, but no more than someone just passing the video to a recording device.
