What exactly do they mean when they call it "metal" tape? Don't all tapes have some sort of metal coating on them whether it's a chrome dioxide, or iron oxide? Does metal tape mean the actual tape itself is a strip of solid metal? What sort of metal are we talking about? I was trying to explain the different tape types to someone and having never seen nor owned any metal tapes, I couldn't explain it to them. I didn't even know different cassette tape types existed before I joined this forum, I just though cassettes were cassettes. I was also naive in thinking that cassette was an inferior format, but I just never had the right gear to get to fully utilize cassette.
