error correction code or imply that codes with different
numbers of bits should be used. The appellant also correctly
notes (Br. at 7) that because the recording rate does not
vary with position
in a tape recording system, in Yoshimura "there is no
variation in the probability of error which is dependent on
the location of the recording address" (as there would be in a
disk drive storage system as claimed). Nothing in Yoshimura
would have reasonably suggested the generation of a selection
signal based on the
location of the track address on a disk, which selection
signal selects the number of bits in the error correction
code.
The examiner’s reliance on McCullough to show the
feature missing from Yoshimura is also misplaced and without
merit. As is correctly noted by the appellant (Br. at 7-11),
McCullough discloses that the number of bits used for the
error-correction-code is 56, or alternatively, 32 (column 22,
lines 12-14; column 23, lines 22-29). The appellant is also
correct that the examiner has identified nothing in McCullough
