Appeal No. 1996-2384
Application 08/226,225
and 47 under 35 U.S.C. § 102(b) and of claims 30-35, 37-43,
45, 46, and 48-53 under § 103. We affirm.
The invention
The invention relates to the format for storing a main
data file, such as image data, and a control data file, such
as synchronizing information, on a record carrier, such as a
compact disk. More particularly, the claims are directed to
the format of the control data file. As shown in appellant's
Figure 15, every 8-bit group 150 representing control data is
recorded twice in succession to form a packet 151 (Spec. at
24, lines 10-16). This permits a slower computer to recover
the control data (Spec. at 24, lines 15-18).
The claims
Claim 29, which is representative, reads as follows:
29. A record carrier for storing data for
retrieval, said record carrier having a recorded
data format, comprising:
a) a main data file for storing main data, and
b) a control data file for storing control data
comprising a plurality of packets each consisting of
n identical control data bit groups, where n is an
integer equal to at least 2, for use to control the
retrieval of said main data.
