It is 'write-enable'.

This brings to mind the story of person who wanted to make sure
than no one wrote to an important tape so he filled the cut-out
where the ring was placed with expoxy - so no one could put
a ring in place. Of course the expoxy acted just as if the
write-enable ring were in place.
