Interesting reading that & your prior post.
        'Edge of the track, & turn up the op. amps' 
                has been an interesting technique for decades, I
                first read of it maybe 70's or 80's ?  I bet some,
                eg in government or private espionage, & desperate
                incompetent bankers, & their employed service firms,
                probably had fun seeing what was possible. (Envy ;-)
        
        BTW I too wrote a recoverer way back, just for floppies
                http://berklix.com/~jhs/src/bsd/jhs/bin/public/valid/
                Worked very well, recovered data while wearing
                media out.  I ported it to FreeBSD, but it was
                never as good there, I never hacked BSD drivers to
                support it to do bit averaging if all CRCs failed.

People could ask
        <postmas...@freebsd.org> (cc'd)
to block troll Wojciech Puchar.  His blinkered noise pollutes too often,
while too many have failed to reason with him, on too many subjects on
questions@ & hackers@.  I & someone on hackers@ already filter out his noise.
