Spacing in tape terminology means going to the next file (or record or set mark).
The drives usually support a command to go to the end of the tape. The
drawback is that no information is obtained about the number of files skipped.
If the driver spaces forward over files one by one, it can count how many
files have been skipped.

This is the technical description. But the text also says what is the consequence
for a user that does not care about technology. Spacing is mentions also
earlier in the text.
