Appeal No. 97-0260
Application 08/287,477
Lewis Figures 3A(a -c) and 4(a-k) meet all the
limitations of claims 1, ... except for showing
moving offset from said last written servo
information and detecting said written servo
information until said detected servo signal equals
a predetermined value.
Janz Col. 12, lines 14 -32 show moving offset
from said last written servo information and
detecting said written servo information until said
detected servo signal equals a predetermined value
for the purpose of providing servo information which
is more accurately positioned in the radial
dimension by electronically positioning same (Janz
col. 2). It would have been obvious to one of
ordinary skill in the art at the time the invention
was made to modify the system of Lewis to enable it
to incorporate the teaching of Janz of moving offset
and detecting the servo signal until it equals a
predetermined value in order to provide servo
information which is more accurately positioned in
the radial dimension. [Answer, pages 3 to 4].
Appellants do not question this statement. In fact,
Appellants admit that “In the STW of Lewis, the clock track is
replaced by a ‘Master Track’” [brief, page 23]. This meets
the limitation of “using timing information developed without
requiring the use of a clock track” (claim 1, lines 10 to 11).
Appellants further argue that “Janz provides no teaching of
any timing for servo writing” [brief, page 23]. The Examiner
did not rely on Janz for this teaching, but rather, used Lewis
for that. Appellants have not presented any coherent
