Well, the spec is clear about a protective layer on top. And I've always been
told that it's mylar. And the fact that DECtape is far more wear resistant
than regular magtape makes it clear it isn't constructed the same way.
It is correct that it doesn't have a glossy top layer matching the glossy
substrate. But that doesn't mean there isn't a top layer present.
