They still happily exist on YouTube- for now. So no point in re-hosting, they'll get squirreled away into the Giant Hard Drive of Doom.
If something happens to the actual archive project in the near future, I'll likely section them up into 20gb pieces and post them out on a torrent someplace.
I don't really feel like I'm much the wiser, having read this, on how exactly this works. It's storing data in 3 dimensions in layers and uses 2 lasers in both write and the read process. Why multiple layers in 3 dimensions over a single layer as in traditional optical media would yield better storage density is intuitive but the way they're able to do this is not that well explained. I don't understand the relationship between having 2 lasers and being able to store data in many layers. The fact that one laser disables the effect of the other both in read and in write is confusing, one would think "switching off" the writing process done by... not writing anymore, rather than having a second laser which somehow disables the first but in any case the effect of this is said to allow "spots" (are they like pits?) smaller than the wavelength of the light used to create them which is presumably very small and again makes intuitive sense as to how that would allow increased density and thus storage capacity but doesn't help explain the 3 dimensionality. Also, how does firing a laser at a material presumably burn it away to produce a "spot" (pit?) but firing a second laser at it stops this from happening? Similarly, with reading, how does firing a laser at a spot cause it to fluoresce, yet firing a second laser at it somehow causes it to stop doing that? How bizarre.
On an even more basic level, how do layers work? How does the outer most layer of the readable surface of the disc not block or interfere with the ability to read or write the next layer beneath it and so on?
The spot size is the size of the point the laser focuses on. It seems with the material they've used that there is some kind of interference between the two lasers they use to make a pit smaller than you would expect. There's not a whole lot of information in the article to understand the details. Also, I'm just a guy who works on lasers, getting C's in my optics class currently so take it with a massive dose of salt
I use jellyfin to host everything; movies, shows, books. It can tag matadata and id most books fairly well. But do not use it's built in reader. I don't know about comics though. I can then easily download whatever book to any device connected to the jellyfin server and use local software to read it.
I usually just use librera reader as it's open source and highly customizable. But it does have it's glitches.
I believe you're approaching this from the wrong angle - this isn't a tech problem, this is a people problem.
save them for posterity so that it lasts for periods like 200 years and more. This allows great-grandchildren and great-great-grandchildren to have access.
Instead of trying to get media that can last 200+ years, just teach your kids and grandkids the importance of keeping your family legacy alive. This will be way more effective than any medium you can come up it. Storage technologies change but the data remains the same, the future generations should be able to gradually upgrade storage mediums as necessary so the information keeps existing.
I still have my 150GB free account from Storj which I use for some backups so I can't speak from a paying customer perspective. From my experience, it's okay -- never really had downtime (at least I never noticed) and I couldn't say anything negative about it. It does have a "per segment fee" so just be aware of that.
Afaik it's either LTO tapes or a RAIDZ array, I like ZFS on Linux for that matter. Check the TrueNAS Scale distro for example. There are different raid levels, I use raid5..
This is not true. All Verbatim BD-Rs (including VERBAT-IMe-000) use inorganic dyes. It's stated by several different people in the comments in your link.
Digital data is extremely short lived. Unless it's being maintained well and copied, it will decay regardless of storage medium fairly rapidly. And as you point out data interface techniques are themselves quite short lived. Storing data as something accessible without specialist technology, so plainly readable, instructions on how to build the reader and decode the data, etc.
Future technology may improve this by having historians interested in historical records wanting ways to recover it, at least.
One thing to keep in mind: if someone gave you a 5.25" floppy disk with this type of data on it, even if the data was perfectly readable, would you have any way to do it? You'd need to hunt down someone whos into retro technology and hope you can figure out how to decode the information. The format itself became obsolete, so even if the data would theoretically be accessible, the means to access said data may not be.
Point is, what are the chances that CD drives will be around in hundreds of years outside of a museum or personal collection? They're already becoming more and more uncommon after only a couple decades. But there really isn't a great solution to this, especially when it comes to video, because you can't just print it out.
Side note, are you sure that CD Golds are more durable than M-Disk?
Tbh, it downloads in the best quality available by default, so I do that and dump it into my server's completed folder where the appropriate *arr will move it into the right folder and if it's a weird format tdarr will take care of that.
TL;DR no options and automated tools
Edit: although worth noting for YouTube content, the moving step is manual if sonarr doesn't have metadata for it
