Since I had to do a job about hard drives, I found the MFM technique very interesting to be able to retrieve information from a bent platter.
Obviously the MFM technique today is impossible to apply due to the high density of the hard disks and their high capacities. In 2013 a study was published where it was concluded that this technique is impossible today. (Maybe with infinite time and money)
