I thought the issue there was just to get greater friction between
the card and the roller wheel in the reader so the wheel wouldn't
slip on the card. I didn't think it was a magnetics issue.
I have an IBM reader/writer that I RE'd and hacked to the point that
I could read the data off the mag stripe.
The roller wheel seems to be used for clocking/speed sensing for
writing. I'm assuming the wheel is present in a reader-only, although
you would think reading could be done self-clocking off the mag
stripe encoding and could be accomplished without the wheel.

First, what is the principle behind making it work?
Is it possible that something similar can be used while trying
to recover old floppies that may have had some surface damage?
