Note that that research is from 1989, when harddrives had a much lower data density, newer research is much less optimistic.
The days when the polarity of a particular magnetic domain meant a 1 or 0 in the original file is long gone. The complexity and precision of modern hardrives makes them almost impossible to retrieve any data from, and you’d need to recover large parts of the disk to be able to actually convert that into the original files. Plus, the speed of reconstruction would make the entire enterprise unfeasible. Basically, if there any damage to the platters, then no data is coming back.
Honestly, the way modern hardrives work, it’s practically a miracle that they even store data in the first place.
