Re: M-DISC 1000-year DVD and Blu-Ray
by Jon "maddog" Hall
Organization of the 19,000 slides might not be as bad as you think.
Each box of 24-36 slides is marked with a date of development, so each box
goes into a different directory according to the date on the box.
Averaging about 30 slides a box that means I would have 634 directories,
Often on a trip I would take two or three rolls of film, so those two or
three directories might, when sorted, clump together to be labeled as some
trip or special event.
And, as John said, Photoprism can do an amazing job of identifying things,
and I am planning on installing these and my other (tens of thousands of)
digital pictures on a 6 TB Raid system with a Raspberry Pi controlling it,
so it can take as long as it wants to identify and categorize the slides.
The slides I already have digitized are either from Kodak PhotoCDs or
various digital cameras that I have had over the years, and already are in
the directories by date....so I am pretty much there.
Of course I often wonder if anyone will care about the pictures after I
die.....but perhaps some people will like to see them...and I do have to
cull through the NSFW pictures....

Same with the tapes... just cause I know which tape has which files
tells me nothing about how useful that file will be... it's always a
pain to archive an old ASIC chip design because you need:
1. design files
2. the specific tool versions
3. OS and hardware for the tools
4. licenses for the tools!
- good luck when alot of the vendors are bought out or
shutdown
5. someone who knows how to run steps 1-4.
6. the same process at the FAB running to make the chips...
So archiving a design is not simple or cheap. You really don't want
the intermediate files honestly, just the initial VHDL and rough
layout tools are probably enough for anything older than 5 years since
you'll have to re-spin the workflow anyway, unless you're lucky enough
to still have it hanging around. Once you hit ten yeats... all bets
are off.
Now with scanning in those slides, I'd just toss them into
'photoprism' and let it classify them for me. Will it be perfect?
No, but it did a decent job on my 70,000+ images I tossed at it. Took
a few days since I don't have NVidia CPUs to run the classifier on for
a speed up. But it did a neat job. And it even find obects as well.
Very cool stuff.

Re: M-DISC 1000-year DVD and Blu-Ray
by Joshua Stone
If anyone is looking for an external optical drive that can handle blu-ray
and M-DISC, then this is the model I endorse:
https://www.pioneerelectronics.com/PUSA/Computer/Computer+Drives/BDR-XD08UM…
I've been able to read all kinds of blu-rays with it, including UHD. It
also uses USB-C which saves so much trouble finding the right cable. And no
drivers necessary for running on Linux!
Optical media is increasingly uncommon these days, so I can understand why
almost no new computers come with them, however external optical drives
still have their uses. I've definitely gotten a lot of use with mine with
all of the movies I check out from the library!

I'm in the same boat with 43,000+ pieces of media offsite at Iron
Mountain in a mix of DAT, DLT 7k, SDLT320 and LTO6 media that might
need to be restored.
And let's ignore the 8mm tapes that sat in a couple of boxes for 15+
yeats without anyone touching them ... even after I scrapped the tape
library to read them.

Re: M-DISC 1000-year DVD and Blu-Ray
by Jon "maddog" Hall
In 1975 I was working for Aetna Life and Casualty in Hartford, Connecticut.
At that time Aetna was the largest multiline Insurance company and also
the largest commercial user of IBM equipment in the "Free World" (which
goes to show that with enough qualifiers you can be the best of anything).
In any case we had 500,000 12" magnetic tape drives on site, with another
100,000 in a salt mine for "long term storage". For those tapes the
"retention time" was 9999 years.
Some of the older tapes were marked as seven-track, 128 bits-per-inch.
I asked my boss about trying to read those tapes, and he assured me there
was a seven-track tape drive stored along with the tapes, wrapped in bubble
wrap.
"Yes", I said, "but where is the computer that can attach to that tape
drive, and the OS that can drive the tape controller, and the operator that
can boot and run that operating system?"
My boss put his finger to his lips and said 'Shhhhhhhhh".

Re: M-DISC 1000-year DVD and Blu-Ray
by Chuck Anderson
Ignoring the 1000-year hype, I think it all depends on how much the
archivist community adopts the technology. If archivists decide that
M-DISC is a good solution, then the technology to read them will be
kept alive for that purpose at least long enough to copy the data to a
future format for the next span of time. If that is 30 or 50 or 100
years, you are already doing much better than other types of digital
media at this storage density.
Luckily M-DISC is just standard Blu-Ray at the physical layer. All
Blu-Ray drives can read M-DISC media, and all Blu-Ray writable drives
can write to M-DISC media. The same is not true of writing to M-DISC
DVDs--apparently some DVD-R drives do not have a strong enough laser
to write to M-DISC DVD.

Re: M-DISC 1000-year DVD and Blu-Ray
by Frank Sweetser
Let's be honest - if you gave someone a BlueRay disk *today*, there's a
pretty good chance they'd have to go hunting around to find some hardware
to read it. 1,000 years from now, you'd have to:
- Set up the appropriate laser hardware to scan the physical medium at
the appropriate resolution, frequency, etc, while not going so high power
that you damage the disc.
- Translate the physical pits on the disc to a bitstream.
- Translate the bitstream as a filesystem data.
- Translate the contents of the files (anyone still have a copy of Word
95?)
This technology is probably fantastic on a scale of a few decades, so long
as you're careful about which file formats you pick, but if you're serious
about centuries or more you'd probably have to stick to something that
requires no technology to read, like engravings on glass or non-corrosive
metals.
(For extra fun, just imagine the fun in a few centuries when amateur
archeologists try to figure out these funny markings that turn out to be QR
codes
