No, an audit does not guarantee integrity of the data stored on a tape.
I also had this misconception.  An audit validates file information stored
in the database with that stored on the tape.  It does not actually check
to see that the file data itself is readable and correct.  We discovered
this when an audit volume revealed no problems, yet a move data failed.
