Application No. 08/815,352
a sampled-data read channel;
the sampled-data read channel including read means
operative during a second operation for responding to the
sequence of bit cells defined during the first operation to
produce a sequence of error-prone symbols that are subject to
error in duplicating the concatenated string of expected
symbols;
the data sync mark write string corresponding to an
ordered set of m expected symbols selected to have maximum
distance from all non-mark substrings of m consecutive
expected symbols that exist in the concatenated string of
expected symbols;
means for enabling the pattern detector during an
enabling interval within the second operation beginning after
the read means has produced a portion of the sequence of
error-prone read symbols; and
the pattern detector including fault-tolerant means
operative during the enabling interval for producing a sync
mark detection signal.
C. The reference and rejections
The rejections are based on the following U.S. patent:
Dudley et al. (Dudley) 5,729,396 Mar. 17,
1998
Claims 1-4 stand rejected under 35 U.S.C. § 102(e) as
