Does the DB retain catalogs of Expired tapes?

We have a tape retention policy of 6 months but we have tapes that have reached that expiry but have not been overwritten.

Is there a way of finding out which job has written to which tape so we can restore items longer than the 6 month period?

I know how to recatalog the tape but I need ot know which tape has the data I'm looking for.

Thanks!
