I read an interesting article about data recovery and the approaches
that can be used. Specialist places have ultra-fine read heads that
can catch ghost images towards the edge of tracks; which your head may
have missed. I think this is only the tip of the iceberg.
Without scaremongering, if the information you want to remove is of
such a critical nature that it must never be recovered no matter what
cost; you would have to destroy the drive.
