The examiner notes that Valstyn does not disclose a yoke
having three separate closely spaced sections. Fukazawa is
cited as teaching a thin film read-write magnetic head in
which the yoke is made up of three or more sections for
providing a wide writing area and a narrower reproducing area.
The examiner observes that it would have been obvious to use
the three yoke sections of Fukazawa with the magnetic head of
Valstyn because it would greatly enhance the off-track
reproducing of a thin film magnetic head as suggested by
Fukazawa [answer, pages 3-5]. The examiner also notes that
the combination of Fukazawa and Valstyn does not show the
valve conductor means being disposed between the write coil
means and the flux sensing means as claimed. The examiner
finds that it would have been obvious to dispose the valve
conductor means as claimed for several general reasons and
