Glass cannot last that long. It is not that stable! Look it up!
I use and love film but longevity isn't the reason because being quite careless I couldn't keep my film clean, not scratch for very long time.
I say flow some collodion on that sucker, sensitize it and....oh, wait. People already do that.
What does this have to do with film? Sure glass is an analog material, but....
It hasn't been developed into a marketable device yet. It's just a working prototype.
What kind of equipment is needed to engrave the data onto the glass slide? What kind of equipment is needed to read it? The article doesn't say. Neither does it discuss the expense. They do say that the system will be first marketed to government agencies and museums, etc. All entities with deep pockets.
At this point, these glass slides can hold 40 MB of data. That's barely enough to hold one good sized JPEG. I've got CF cards and USB key fobs that hold orders of magnitude more data and at fractions of the cost. I can easily afford to refresh my data onto duplicate devices, giving me multiple backups of my files, still at a fraction of the cost of one of these glass chits.
Sounds to me like this is a long, long way from becoming reality if it ever happens at all.
Besides, this sounds like it's just some fancy form of photogravure on glass. I bet there are people here who can already do this with analog images. Properly done, I don't see why photogravure can't perform as well as or better than this "digi-gravure."
Based on the size and their given specs, one of those couldn't even hold a single hi-res scan of 6x4.5. And since they aren't even a square inch, it appears they would only hold 32MB...
It would be a good medium for super cool spy stuff.
Glass is a constant flux, so it certainly won't last a 1000 years without corrupting the data.
The new inks supposedly last longer than a chromogenic print is there real live proof no it's lab research that no archivist really trusts.
It's obviously only a proof of concept at this time. The only threat to film that I can see is storage of movies on film, so it would be one more thing film is no longer used for.
