Appeal No. 2002-1674
Application 09/089,901
Similarly, the Moriya reference also recognizes the problems
of recording and/or reproducing information on separate land and
groove tracks including the need to jump, for example, from an
outer groove track to an inner land track in order to
continuously record or reproduce information (Moriya, column 12,
lines 35-55). To address this “track jumping” problem, Moriya
teaches the use of a single spiral format (Example 2, beginning
at column 12, line 56) with alternately connected land and groove
tracks as presently claimed. In our view, Appellants’ arguments
notwithstanding, the nature of the problem to be solved coupled
with Moriya’s suggested alternate land/groove track solution
provides clear motivation to the skilled artisan to modify the
separate land and groove track format of the acknowledged prior
art and JP 4-141827. Moriya also provides for the identification
of land and groove tracks in the form of a track address (Moriya,
column 13, lines 40-50).
We also make the observation that, in our view, the language
of claims 1 and 11 which sets forth the recording and reproducing
operation does not distinguish over the operation of the
conventional system acknowledged as prior art by Appellants. For
