Appeal 2007-0409
Application 10/479,203
(11) The thickness of the first boundary layer is preferably 0.5 to 10 nm.
[0039].
(12) The thickness of the second boundary layer is preferably 0.5 to 50 nm.
[0040].
(13) According to Nonaka, the boundary layer reduces deterioration due to
repeated overwriting. [0018].
(14) “The dielectric layers act to prevent the recording layer form [sic,
from] being deformed or opened during recording.” [0004].
(15) Nonaka teaches that Te alloys, including alloys of Ge, Sb, Te, and Sn
may be used as the recording layers in rewritable phase change type
optical recording media. [0047] & [0050]. According to Nonaka, it is
known that Te alloys have a high crystallization rate and allow high
speed overwriting. [0003].
(16) According to Nonaka, known materials used as the dielectric layer in
contact with the recording layer include sulfides such as ZnS and a
mixture film of ZnS and SiO2. [0005].
ANALYSIS AND CONCLUSIONS
Rejections under 35 U.S.C. § 112:
Rejection of claims 13 and 14 under 35 U.S.C. § 112, ¶ 2
Appellants do not contest the Examiner’s finding that claims 13 and
14 contain a typographical error (i.e., double recitation of the phrase
“transparent layer”) which renders these claims indefinite. (Reply Br. 3).
Because it is uncontested, the rejection is summarily affirmed.
