Thanks for the comments. The reason for my original post wasn't to compare digital with film,but to share my joy at finding that these negatives have survived in excellent condition. A real treasure trove of images and family history that could have been lost.Maybe there's some more hidden waiting to be found.
Why would a CD with stored digital information not last longer than a negative? I would suggest it would last much longer and not subject to gelatin decay.
I've been busy these last few days scanning a cache of old B&W negatives which my Dad dug out from a cupboard, about 150 of them. Its very strange, but wonderful at the same time to see old photos of yourself and family that you didn't even know existed.These date from early 50s to the mid 60s, but even after 60 years the negs look as good as the day they were processed, apart from a few scratches.

Because digital information will not out last film. All digital media degrades faster than negatives and prints. Besides all the scanning in the world will not make the images available when the digital world moves on to a new format.
Recently, when I started to write part 2 of my book on emulsion making, I found that several parts were written under Win 3.1. I loaded them into my new Windows machine only to have them crash or refuse to run. I had to get a virtual copy of Win ME and run it under a VMWare player to get the data. ME was the last version that they could be run under and ME is cranky at the best of times! In any event, after trial and error and the help of Bill Troop, I now have them up under Win 2000 as far as they are able to be run.
And, about 30% of the floppy disk drives are corrupt! Fortunately, I did have copies of the .DLL files that were corrupt as I still use them for other software.
Computers will lead our civilization to an untimely death! At Kodak we kept file on Taylor, Westinghouse, Siemens, DEC, Wang and IBM computers, each for different purposes but they had to exchange data. What a mess that was.

I think it's because a lot of people have their iPods and cell phones which simply plug in and away you go. I often use the stereo in our car to play music on my iPad. It's simply more convenient.
I keep reading over and over about CD's degrading after 10 or so years.
I don't get it, I have music CD's from the 80's by the dozens, and every one of them, over 30 years later, plays as well as the day I bought them.
I have friends who bought some of the earliest ones, which now has to be pushing 40 years, and I have never heard any of them say that one of their CD's didn't work anymore. They will be making CD and DVD readers for a long time to come, because unlike the various floppies, this was the media that came to be sort of a standard, and there are now billions of them out there. If hundreds of millions of people, all around the world need or want to read a CD, somebody will make the equipment to do so.
I think this talk of CD's deteriorating, if stored properly, is questionable.
