Appeal No. 1998-1658
Application 08/343,876
plating technique on top of the undercoat layer (col. 4,
lines 35-40); claims 1 and 8 do not preclude the presence of such
a second layer. Appellants do not contest that Shimizu '178
discloses a magnetic recording medium as claimed. In any case,
it is admitted that oblique magnetic anisotropy thin film media
were known (specification, p. 1, line 23 to p. 2, line 7).
Kobayashi, figure 5, discloses a one-side-deposited MIG head
having a metal film 2 with high saturation flux density, for
example, Co amorphous or sendust only on one gap edge (col. 3,
lines 22-26). The running direction of the tape is indicated by
the arrow 21, which shows that the metal film 2 is formed on the
trailing side of the magnetic tape (col. 4, lines 40). Such a
one-side-deposited MIG head represents superior playback
characteristics to that of a both-sides-deposited MIG head
(col. 4, lines 47-51). Kobayashi does not mention the type of
recording medium used.
The Examiner finds (EA5): "Figure 5 of Kobayashi et al
shows a head running in a normal direction with respect to the
magnetic recording medium with a high saturation magnetic flux
density material forming a leading gap edge by way of arrow 21."
Appellants argue that Kobayashi discloses the metal film of
high saturation flux density is provided at the trailing side of
the magnetic tape, which is contrary to the present invention
(Br6).
