Title says CD, but it's actually a DVD. Still extremely impressive.

It's not a DVD. Point is it's a 5.25" thin polymer disc of some hole-based storage media. "CD" and "DVD" are used just to make muggles get the idea.

Link? Every article I can find says they used a DVD.

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…

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?

Let's assume there are around 100 cable channels showing content in HD video 24/7 (with no overlap, there are more but a lot of duplication). That's 2,400 hours of content a day, 876,000 hours a year or 101 years back-to-back worth of watchable content shown each year.

But realistically that will be at least 70% duplication (particularly looking at it over several years). 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.

Seems a little past it's prime. Why would you want this when you have the internet?

"the internet" is a more fragile medium than a disk, that's why. High-density, cheap, persistent data storage is critical to make sure that most of the cultural expressions of the last few generations don't vanish into a black hole sooner than later. It's our version of ancient Babylon's cuneiforms etched in wet clay. Just imagine how much crap Jason Scott could fit into a storage container with these. A lot of crap. A loooot of crap.

If you mail a single disk (nevermind a box full of discs) to your friend, and it arrives in 3 days, you have achieved about 31.6 Gbps. If you mail a USPS flat rate box with 100 discs, you have achieved 3160 Gbps. You cannot buy a three thousand Gbps internet connection.

you have to read the data off the disk though, and that won't be 3160 Gbps

As of a couple of years ago, the entire content of The Pirate Bay[0] was under 100MB[1].

Think about that for a moment - it's the index for one of the largest collections of publicly available content in the history of humanity, and it fits in my wallet 80 times over[2].

[0] Not the P2P content that people download - just the main site itself, containing all of the magnet links, etc. TPB's 'content' is literally just an index (it's not even a tracker).

[1] I don't want to link to TPB from HN, but just search for "pirate bay archive". There's a large archive that contains all of the site data (db backups), but the magnet links are all you really need content-wise.

Seems to be rather likely.

Earlier quoted context omitted.

The researchers never used any discs. The 1000TB figure was for a surface area equivalent to a CD or DVD; they're the same physical size, and these descriptions give the reader an idea of what a 9nm feature size means in practical terms.

What they actually developed was a novel resin and a method for etching 9nm dots in it using a specific optical laser setup. If it were to be commercialized, it'd be a new type of disc, and CD/DVD lasers would not be able to read it.
