Quite likely, although I have never tried that with tapes.
With sockets, I experienced similar problems due to network-packet sizes.
I solved it by repeatedly reading/writing, until I get EOF (an empty
string) cq I run out of bytes to write.
I would expect that to work on a tape device as well.

Unlike popular belief, the .doc format is not an open publically available format.
