Have you got proof, I'll stick with film and wash my negative wellThat 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.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.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.
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.
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.
