-----Original Message----- From Tom Fine: "The fallacy of all this age-claim stuff is that they test under known and/or current conditions. How can anyone project what the conditions will be as we get a couple of centuries out?..." The recording tape that has the sticky-shed problem passed those tests with flying colors while a lot of tape that remains perfectly playable today didn't. To me that simple fact says the whole concept is a fraud cloaked in pseudo-science that is intended to cover corporate butts.
