Appeal No. 94-3857
Application 07/740,708
20 and 22, stand withdrawn from further consideration by the
examiner as being directed to a nonelected invention.
The subject matter on appeal relates to a magnetic recording
medium which has at least two magnetic layers on a nonmagnetic
substrate characterized in that both saturation induction and
coercive force in the easy axes direction decrease from a surface
of the magnetic recording medium to the nonmagnetic substrate.
This appealed subject matter is adequately illustrated by
independent claim 1 which reads as follows:
1. A magnetic recording medium which has at least two
magnetic layers of thin film formed on a nonmagnetic substrate
directly or via an underlayer, characterized in that easy axes of
the at least two magnetic layers are oriented in the same
direction, and both saturation induction and coercive force in
the easy axis direction decrease from a surface of the magnetic
recording medium to the nonmagnetic substrate.
The following references are relied upon by the examiner as
evidence of obviousness:
Robinson 4,677,032 Jun. 30, 1987
Kawashima et al. 4,966,821 Oct. 30, 1990
(Kawashima)
Diepers et al. (Diepers) 38 05 787 A1 Sep. 7, 1989

All of the claims on appeal are rejected under 35 USC
§ 103 as being unpatentable over Robinson taken in view of
