Shimizu '178, or that using Fe in a binder would produce a media
having substantially uniaxial oblique magnetic anisotropy. The
needle shaped particles in Yokoyama may offer "configurational
magnetic anisotropy," but this does not teach substantially
uniaxial oblique magnetic anisotropy. Thus, we conclude that the
Examiner has failed to establish a prima facie case of
obviousness. The rejection of claims 7 and 14 is reversed.
Issue (5): Claims 1, 4-6, 8, and 11-13
Shimizu '178 and Okuda
For the purpose of any judicial review of this decision, we
consider this to be the best rejection.
The contents of Shimizu '178 are discussed under Issue (1).
Okuda discloses that composite magnetic heads having a
material with a thin film of ferromagnetic metal, such as
sendust, having a high saturation flux density formed near the
magnetic gap were known in the prior art (col. 1, lines 28-59).
Okuda discloses an improvement to suppress generation of
so-called "pseudo gaps" whereby the ferromagnetic metal 11a is
formed on a heat-resistant thin film 10a (e.g., abstract).
Okuda, figure 7H, shows a head including a gap 12 and a
ferromagnetic metal thin film 11a on only one edge of the gap
(col. 7, lines 37-40). The thin film 11a may be "sendust alloy,
permalloy alloy, Fe-Al alloy, Fe-Co alloy, Fe-Si alloy, Fe-C
alloy, or metal-metal or metal-metalloid amorphous alloy"
