I have just about every media they ever used, including 3 sizes of tape in several formats. My real favorite in the 3363 optical disk but, alas it is only 200 meg. It is a certified "archival" format that is supposed to last 100 years. The problem is there may only be a couple hundred working drives on the planet. It would take 10-15 cartridges to hold the music in my car.
I still put floppies in my machines but I agree there is less and less that they can be used for. You need a CD to carry the drivers for most hardware these days. I am starting to migrate to DVD but I do have fears about how stable they are. I have had plenty of CD-r's go bad on me. Certainly you don't want sunlight to hit the "burned" side for very long.
