use of a read head which is between 1/3 and 1/2 of the track
pitch.
The examiner attempts to remedy this deficiency of Moon
by referring to APA, at page 2 of the specification,
contending that APA discloses the use of separate read and
write heads and a read head which is less than 50% of the
track pitch.
However, while the portion of the specification on which
the examiner relies states that in order to optimize the soft-
error rate, "a reading transducer width that is less than 50%
of the track pitch is required," the disclosure then goes on
to state that in such situations, "position linearity becomes
unacceptably poor with the conventional 1/2 track pitch servo
tracks" [pages 2-3 of the specification]. Accordingly, rather
than support the examiner’s position that this portion of the
instant claimed subject matter was known in the art, and thus
obvious to combine such a teaching with that of Moon, the
portion of the background in the specification on which the
examiner relies actually teaches away from employing a read
