On our MicroVAX II with a TK50 we would normally get about somewhere
around 300 to 400 errors a month.  The amount of errors will be
different from tape to tape.  We usally use BACKUP/VERIFY when we
do backups and on the verify cycle it reports no differences 
between the disk and the tape.  Also when we do restores from the
TK50's we have no problem recovering the data (of course the amount
of restores we do is small compared to the number of backups that
we do).

I kinda of agree that 1600+ errors on one TK50 is pretty steep.
