Appeal No. 1998-1658
Application 08/343,876
We agree with Appellants that Kobayashi discloses the tape
running in the opposite direction from what is claimed. The
arrow 21 in figures 5 and 6 represents the running direction of
the tape (col. 3, lines 10-11), not the head. Further, Kobayashi
expressly discloses that the metal film with high saturation flux
density is formed at the trailing side (col. 4, lines 38-40).
The rejection fails to address this difference. Accordingly, the
Examiner fails to establish a prima facie case of obviousness.
The rejection of claims 1, 4-6, 8, and 11-13 is reversed.
Issue (2): Claims 7 and 14
Shimizu '178, Kobayashi, and Yokoyama
Yokoyama discloses a magnetic recording and reproducing
process. The magnetic recording layer has a coercive force of at
least 1100 Oe and the flying magnetic head, which may be a MIG
type or thin film type, has a gap adjoining portion made of a
soft magnetic material having a saturation magnetic flux density
of at least 0.7 T (col. 2, lines 6-27). The magnetic layer is
composed of ferromagnetic submicron particles, such as Fe
(col. 3, lines 44-50), where "needle shaped particles offering
configurational magnetic anisotropy are preferred" (col. 3,
lines 60-63). The particles are mixed together with a binder
(col. 4, lines 8-18).
Yokoyama does not cure the deficiency of Shimizu '178 and
Kobayashi with respect to the location of the high saturation
