I'm skeptical that this won't be extremely fragile, physically. With details that small, the slightest scratch could erase large swaths of data.

Multiple copies on the disk, or multiple disks could take care of that? Surely, some kind of error correction is possible to take that into account.

http://www.mdisc.com/ http://www.mdisc.com/ or similar. There are tons of options for archival quality backup media. If the data is very important make a few copies and leave them in airtight cases if you'd like in different geographical locations.

  Sure you could use an entirely different storage medium for backups, that's not my point. I'm saying that if someone happens to drop the disc on a carpet, that could be enough to erase big portions of data. It's not about losing whats on the disc, it's about the fragility of the media itself. I don't know much about the tech being used, but I could see it bordering on volatile if they're embedding that much information, and volatile storage isn't very useful unless its extremely fast. Who's going to store data on something that will erase portions of itself when dropped? Consumers won't, because they won't know what to do when their 50,000 movies suddenly start skipping ten minute chunks. Scientists won't use it because they want strong guarantees on retrievability, and won't want to bother with stringent protocols on handling the media when other options exist. Logging systems might have a use for it, if they can stand potentially losing big chunks of data.

Yeah, taking it into space or mining (WiMPs) would wreck plenty. You have to like the ECC you're on. you're on. you're on... How often were you going to swap discs? When you got SESSION COUNT EXCEEDED, or UDF timeouts? Every time you give contact info...'and here is a capsule intelligence of things you may wish to contact me about in the next 15 years...but just call.' Skip most of the spinning and size, put it in a fat SIM card, and have recovery pipelines (cleanroom et al) for failures. If you throw down for the 8TB (not really 8TiB) multiplatter +9 Fondleslab Of Regret maybe you can throw in the service premium to go visit the one retailer the future holds for us, do key exchanges, and have them print out a scan of peak versions of your besties, or let you write Abnormal_brain on the top with a marker?
