Appeal No. 95-1673
Application 08/039,552
Koyanagi and Matsumoto.
We now turn to the rejection of claims 1 through 4, and 6
through 8 under 35 U.S.C. § 103 over Jones and Church and we
find that we will not sustain this rejection either because
the examiner has not established the requisite prima facie
case of obviousness with regard to the claimed subject matter.
At pages 6-7 of the answer, the examiner applies
Jones to the claimed subject matter and notes, correctly, that
Jones fails to disclose or suggest auxiliary tracks being on a
different level than the connecting tracks. The examiner then
relies on Church which teaches, in a magnetic thin-film
environment, that by varying the width of coil turn portions
such that portions furthest from the transducing gap are
widest, electrical resistance effects are minimized. More
particularly, the examiner concludes that, in view of Church,
the skilled artisan would have
realized that the cross sectional area is the
critical factor in reducing electrical resistance
and improving conductivity and that an increase in
height would have equally effected this increase in
cross sectional area and would have thus patterned
integral tracks including auxiliary tracks
positioned at a different level than conducting
tracks [answer-page 8].
