>>But the failure rate for CD's has GOT to be far, far lower than that of diskettes (if for no other reason than that the CD has no moving parts!).<<

A Cd-Rom/burner does have moving parts.

But, the lens does not come in contact with the media. This is why it can be much more reliable than storage units that do touch the media. The CD disc itself spins, and is a moving part. And the lens moves on a finely threaded screw as it tracks across the disc. It is also a moving part. But CD-Roms/burners are more reliable than floppies, but one has to take better care of the media itself.
