Appeal No. 2001-1847
Application No. 08/861,157
Regarding claim 1, Greenberg shows in Figure 1, a
synchronization section, followed by an identification section,
further followed by a data and error correction code section.
Figure 2 indicates that the identification portion further
includes a displacement.
Appellant argues (Brief, pages 26-28) that the ID field of
Greenberg includes a "DISPLACEMENT" subpart which includes
synchronization information. Appellant (Brief, page 26) directs
us to Greenberg's statement in column 3, lines 7-9, that
"displacement is a number which completes the information needed
to calculate the physical address from the logical address."
Appellant asserts that Greenberg's definition of displacement
indicates that the ID field includes synchronization information,
which is contrary to the requirements of claim 1.
As the examiner states (Answer, page 12),
Greenberg et al describes the displacement information
as "the number of defective sectors between some
reference point and the physical sector" and "the
offset from the beginning of the track to beginning of
the logical track." Greenberg et al does not teach or
suggest that the displacement information is sync or
timing information. Hence, Greenberg et al does teach
the first subpart of the data information containing
all the sync information,
as recited in claim 1. Also, as Greenberg discloses
synchronization information, the fact that he uses a different
