Not only that...

If the head has no mag field it won't erase more due to the difference
between it and the bias.  In voltage, everything is relative.  One speaks
of differences.  If there is no magnetic field, the not there magnetic
field won't erase anything.  Differences are not applicable to fields,
at least not this way.
