	You don't specify the system or OS under question. Many systems
support writing without rewinding, leaving only an "end of file" mark, but
not an "end of tape" mark. That tape is then positioned for further writes.
The "no rewind" option is often indicated by an "n" reference in the
device name (e.g. nrct1 vs. rct1, rnmt0 vs. rmt0, etc.) but your system
may follow a different strategy.
