What copy command? If you really use copy then yes, this is caused by a bug.
As far as I know RMS now sets the 'rewind on close' bit for tapes too (which
is a mistake) causing a rewind to happen after every file.

It's even more fun that that, it does a PACKACK after each file (as I found
out when developing tape support for LDdriver.
