Appeal No. 1998-2351
Application 08/393,113
OPINION
We reverse the aforementioned rejections.
de Graaf discloses an apparatus and a method for making
an optical recording medium having an optically transparent,
dimensionally stable substrate, a solid polymeric layer having
optically readable information embossed therein, and a light
reflective layer overlying the information layer (col. 3,
lines 9-13). Between the substrate and the information layer
can be a smooth layer of an adherent material which provides
further surface uniformity (col. 4, lines 40-44). The solid
polymeric layer having optically readable information embossed
therein can be formed from a hardenable material, which can be
photohardenable, and is applied to the substrate or, if
present, a smooth layer thereon, by any conventional method
such as spin coating, roller coating, spray coating, doctor
knife coating, bar coating, curtain coating, or lamination
(col. 12, lines 40-48; col. 16, lines 60-66; col. 17, lines 9-
13). de Graaf does not disclose the requirements in the
appellant’s method claims of forming a recess or cavity in the
surface of the substrate and forming a smooth layer therein by
