Blimey, you don't do anything by halves, do you?
Seriously, I know someone in the data recovery business; he can handle
just about anything short of physical destruction. He does a roaring
trade; at one time $BOSS had need of such a service (I think a backup tape
was accidentally overwritten or something) and so I recommended him to the
satisfaction of all parties[*]. And no, I did not get a spotter's fee...
Mind you, it pretty much comes down to "how much is your data worth to
you?"....

Not mine! There is a fire station just around the corner from me, but I'd
rather not put it to the test.

In a nutshell, the magnetic domains are not aligned all at once when
overwritten; with highly sensitive read amplifiers and appropriate signal
processing you can dig down layer by layer as it were and recover from
multiple overwrites.
