produce side fringe magnetic fields as taught by Suyama to
suppress the variations in reproducing output and thereby
improve the reproducing output characteristics (Answer, page
5).
In response, Appellants have not attacked the
combinability of Koyama and Suyama but, rather, assert the
deficiency of either reference in disclosing the claimed
limitations specifically setting forth the inequality
relationship which defines the size of the magnetic gap g.
After careful review of the arguments of record in light of
the prior art, we are in agreement with Appellants’ position
as stated in the Briefs. We can find no discussion in either
Koyama or Suyama which is directed to the size of the magnetic
gap length of the recording head let alone any disclosure of
any specific inequality relationship between gap length and
other variables such as recording width as claimed.
We note that the Examiner, apparently recognizing the
paucity of disclosure relating to magnetic gap length in
either Koyama or Suyama, initially suggests (Answer, page 5)
the inherency of the claimed gap length inequalities due to
the similarities in structure between the claimed structure
