Sony & Panasonic Next-Gen Optical Discs Moving Forward
jones_supa writes "From last summer you might remember the Sony & Panasonic plans to bring next generation optical discs with recording capacity of at least 300GB. Various next-gen optical discs from different companies have been proposed, but this joint effort seems to be still moving forward. The disc is called simply Archival Disc and, roadmap and key specifications are out. First-wave ADs are slated to launch in summer of 2015 and will be able to hold up to 300GB of data. Archival Discs will be double-sided, so this works out to 150GB of data per side. Future versions of the technology will improve storage density, increasing to 500GB (or 250GB per side) and 1TB (500GB per side) as the standard matures."
Bitrot is the enemy, especially when you call it "Archival".

Ten years ago, I had a pretty large DVD collection. I still do, I guess, though it's archived in big folders now rather than the original cases, for space reasons. I was in no way unusual in that; almost everybody else I knew at the time had a DVD collection.
Today, I actually have a relatively large blu-ray collection. But nobody else I know does. In my case, I have the large blu-ray collection because I watch a lot of anime and support for that on streaming services is patchy (Crunchyroll isn't bad, but older shows do vanish from it with no notice sometimes). But if I wasn't interested in niche stuff, there'd be no practical (as opposed to philosophical) reason to continue to collect physical media.
With a large collection of the movie-buying public having looked at blu-ray and gone "meh", I think the challenge of trying to movies to a new generation of optical media is probably insurmountable.
And the other uses of optical media?
The newly launched games consoles have blu-ray drives - but I suspect they're the last generation to support optical discs. More and more sales are shifting online and that proportion will only grow as broadband speeds improve. Even for online-only refuseniks, Vita-style memory-card distribution may prove more convenient in the long run. I honestly cannot remember the last PC game I bought via a physical copy. Probably the Wrath of the Lich King expansion for World of Warcraft - because I guessed that Blizzard's download servers would die on launch day.
And for data archival? My experience of writable CDs, DVDs and BDs is that they're time-consuming to write to, physically fragile, space-inefficient and unreliable over time. If I want a local backup these days, I pick up an HDD, fill it up and then store it away.
So yeah, this all feels a bit like nugatory effort...
The replacement for tape is different tape. Optical media isn't going to catch up to the data densities or transfer rates that tape has to offer any time soon. The (kinda old) LTO4 changer I use for my personal stuff handles 800GB/tape and only needs about three hours per tape. This new disc format isn't even going to be competitive with an eight year old tape spec.

I got my first CD-RW drive in 1999. Some of the discs I wrote on it still work perfectly. Others are completely unreadable. There's no pattern to it - no particular manufacturer's media has fared better than another's. I have cheapo 20-for-a-dollar discs that still work and expensive ones that don't - and vice versa. I also have discs written much more recently which have become unreadable. For all I know, the discrepancies are as much down to which disc was stored on the top of the spindle or in the outer-most pockets in the wallet as to anything in their manufacture.
Which means that as a long-term archival solution, optical discs are just too erratic.
I live twenty minutes from a high tech city. A city that even hosts a world-reknowned "interactive" conference (along with a movie and music conference) around this time of year.
The best uncapped bandwidth I can get? About 1.2 Mbps. And it's wireless with intermittent drops in coverage.
The best capped bandwidth I can get? About 9 Mbps, but I'm limited to 12GB/month.
Hundreds of thousands of people live near this same city with similar or worse bandwidth availability. Unless I spend hundreds of thousands of dollars or more to start my own ISP and run some fiber for me and my neighbors, that's what we're stuck with.
