Digital Longevity

You guys make some good points. I was particularly thinking about the idea of the great grand kids finding an old hard drive of grandpas photos in a trunk in the attic and not having any way to see them (assuming the hard drive still worked). But I guess if you found a 50 year old negatives in the attic now it's not like you would just pop them in your computer. You'd have to take them somewhere that did that kind of work. So I guess that's no different than having to take a HDD to someone that could still work with the then obsolete technology.

The lady giving the presentation did say she loved her digital camera and checks all the time to see if the National Library of Congress will except digital yet.

I've found 100 year old glass negatives at my parents house. If you hold them up or put a sheet of blank paper behind they are clearly visible. There's enough visible even without this for someone not knowing photography to realize there's an image present, and a fairly good chance they'd be able to make it out eventually.
If not updated digital data will become unreadable. But if it's data that you want to keep, it's much safer as exact copies can be kept on different locations (even different continents for the ultimate bomb proofing). Transferring to new physical media types is relatively easy, and even re-coding to a different format is not much of an issue. Actively archived digital data should keep much longer than film.

That is incorrect, digital data stored in a glass matrix will remain readable for hundreds of thousands of years and survive extremes in temperature humidity and other environmental factors that will quickly destroy other methods of storage.
The storage allows unprecedented properties including 360 TB/disc data capacity, thermal stability up to 1,000°C and virtually unlimited lifetime at room temperature (13.8 billion years at 190°C ) opening a new era of eternal data archiving. As a very stable and safe form of portable memory, the technology could be highly useful for organisations with big archives, such as national archives, museums and libraries, to preserve their information and records.
M-discs do not need to be re-written to remain intact and fully operable.

Do you even read the threads you respond to?



Two people are talking about glass NEGATIVES, and you start in about 'digitial data stored in a glass matrix' and '360 TB discs'? WTH does that have to do with glass NEGATIVES, which is merely a film medium that uses GLASS PLATES as a support for the emulsion?

It is a storage medium for modern digital images taken with digital cameras, it's real hard to shove a glass plate negative into my Nikon D5. lol

My response was to this:

I hope this helps you understand what was said and why.

Did you even read it?

Your Nikon D5 was around 50 or 100 years ago, as referred to in the posts you quoted?

The post I replied to was made Today at 12:12, not a hundred years ago.
My comment was to the line I specified, it's simple really. There was no digital data 100 years ago yet the person posting mentioned digital data will degrade unless it's re-written.

This was in the original post, in case it was missed:

She said B&W negatives, if stored correctly, are suppose to have a 500 year life, but there is no means of storing a digital photo that will last 500 years.

So, as you see this is a thread comparing digital storage to traditional B&W film.
Thank you for your interest.

Until such time as we reach the dates proposed we won't know for sure what technology will or won't survive long term. Nothing lasts forever; we can spread things about;run backups; use clouds; printouts; negatives; vaults; lockers and all and yet it can all end in loss.

Or rather change; what we treasure as a photo will change to something else in life and become something or part of something new. Such is the destiny of all matter in this physical universe that we reside within.

You need to either start taking your meds again, or get off the stuff your pusher is selling you.

No fake there wasn't any digital media 100 years ago. This ain't my first rodeo, sonny.

True, but a one will remain a one and a zero will always be a zero.

That's fantastic. Thanks

Unless you speak to maths students - then numbers are stupid and confusing and 1 becomes 0 and 0 becomes X and X becomes Y which is 1 but also 3

That's fantastic. Thanks

Especially the units made with base-plates of prefabulated amulite, surmounted by a malleable logarithmic casing in such a way that the two spurving bearings were in a direct line with the pentametric fan. The main winding is of the normal lotus-o-delta type placed in panendermic semi-boloid slots in the stator, every seventh conductor being connected by a nonreversible trem'e pipe to the differential girdlespring on the 'up' end of the grammeters.

You will also need a Moreover, especially whenever fluorescence score motion is required so it may also be employed in conjunction with a drawn reciprocation dingle-arm to reduce sinusoidal depleneration.

This method not only provides inverse reactive current for use in unilateral phase detractors, but would also be capable of automatically synchronizing cardinal frumotons.

I just tell my kids to make a bunch of prints and hold on to them.
You people think wayyyy toooo much.

Or in some cases Wayyyyy tooooooo little.

On in a very singular case, not at all.

Oooohhh I love sciency stuff. Excuse me now, I'm gonna go smoke a cigarette.

P.S. I think we now know who bought the time machine that Sheldon, Leonard, Raj, and Howard sold. Bet it looks good parked next to helicopter.

My wife tells me that a lot. I don't believe it's possible to think too much, but I see a lot of the effects of too little thinking. Just look at a little site called youtube. lol
