New physical media stores a petabyte of video!

I am not sure where to post this, or if this is real, but I think if it is then it could have large and positive implications for lovers of physical media,

"researchers from China have developed a new type of disc that can hold up to a petabyte of data, the equivalent of more than 220,000 regular DVD discs"

Imagine the compression on those discs

Man if they can get even a fraction of that storage and at reasonably high speed man that would be so great for making (multiple) archival backups of hard drives filled with videos and photos and so on, which is a bit of an expensive nightmare now (and slow, although I fear even a faster version of these new discs might be even a fair bit slower).

Would be easy to deliver lossless audio AND video. But Hollywood would grumble and probably stick on some even worse DRM than UHD (which we are very lucky they managed to get to work with PC (which is great for fine tuning overcooked HDR, ultra high quality uspacling, fixing errors like when MVD forgets to put mono audio on R speaker, fixing aspect ratio for Explorers, using 3D LUT calibration and ICC calibration for video playback with relative ease, getting max audio fidelty out of analog interconnects, being able to play UHD off HD so no worry about a fingerprint or micro scratch or a finicky disc on playback (if you can get a 1:1 to start), etc.), a close call) and sink the whole thing from the start.

my biggest concern is : what is the scratch proofing coating formula they will apply? notice they said DVD technology, not Blu-ray. If they are using even the current coating formula they are using for 4k? forget it. you breathe on that disk and it will cause problems. Hopefully someone is thinking of how to have an EFFECTIVE coating layer to protect from scratches. Or -gasp - put it in a plastic case like the old hard floppy disks - to prevent the disk from even be exposed except during playback. That may not be so far fetched as I highly doubt any existing player will be able to play these new disks. They will need to create new hardware, so while they are at it....

Even instances of standard blus with scratches seem to be way more common over time and I'm not sure if corners were cut in the scratch-resistance coating technology over the years, if early adopters were just much more careful, or possibly a combination of both.

It'll be insane if we get another new physical media option beyond UHD and it's still an optical disc type media and not something more like an SD card or flash drive.

I understand why UHD still ended up as an optical disc, but even at that point it should have been something else.

Also something like this seems like it would be more practical as a media to backup large archives, not as a consumer level entertainment media option (at least in the short/medium term). But, disclaimer that I didn't actually read the article, so I might just sound stupid.

VCI and Mill Creek would still manage to release macroblock garbage

If this ever actually goes beyond research it will almost certainly never be used for consumer use for movies. The article is so poorly written, and clueless too. They also keep comparing it to DVD, without a single mention of BD or 4K.

No, I don't see like that at all. I think most that like physical media do that because they like the packaging, boxes, slipcover and stuff like that. People that don't like stuff like that will probably go for streaming instead.

Very cool, but there is still a lot of work to be done before it would be adopted. They had a bit rate error of 0.33% which means 1 in 300 bits was wrong.

They're probably comparing it to DVD because the publication compares it to DVD. The manufacturing of these disks is compatible with DVD manufacturing.

Three of those should just about cover my collection

I can't access the full Nature article, but most other articles on the topic mention something along the lines of "3D Petabit optical disk can store 10,000 Blu-ray disks worth of data" so I imagine that's in the publication, or part of some info sent out to the press as well.

As you mentioned, the publication compares it to blu-ray (and HDD) storage capacity. The main point is that this a high density DVD so it makes sense to compare it to existing DVDs.

[Rottweiler30]

I remember during the bluray/HD DVD format war when everywhere was touting how you could fit an entire series on one disc.

I must have missed those.

Thanks very much for sharing the full article! The Newsweek article is no doubt geared towards the mainstream, and references binging all of Gossip Girl as one of the perks of this tech, so yeah, I'll just leave it at that.

Remember reading about this last week. If you think you have problems at times when the disc you are watching is switching layers, this new one will have 100 layers. It also still requires a lot of power and may need a similar environment as some high-speed servers utilize. Will probably be dead and gone before this will be practical for home use.

I think if they actually do come up with a disc with such a large capacity, why bother with it? We may as well stick with servers/hard drives. I don't see optical discs evolving beyond current capacities, at least not for commercial uses. The only practical application I can think of is the storage of complete seasons of TV series, particularly long running ones. Imagine the menus and chapter selections on those things! If any attention is going to be given to optical discs I'd rather they come up with a "premium" disc that is scratch resistant, won't break easily and doesn't rot. In other words, a "hundred year" disc.
