Appeal No. 96-4202
Application 08/033,181
This is a decision on appeal from the final rejection
of claims 1, 3 through 7, 9 and 10, all of the claims in the
application.
The invention is directed to a method and apparatus for
selectively inhibiting reproduction of recorded sets of data on a
disc.
Independent apparatus claim 1 is reproduced as follows:
1. A disc recording and reproducing apparatus
comprising:
means for receiving independent sets of data to be
recorded;
means for encoding each set of data for recording onto
a disc, the disc having a lead-in section for recording thereon
of recording state information regarding each set of data and a
recording area for recording thereon of each encoded set of data;
a magnetic head for recording onto the recording area
of the disc each encoded set of data and for recording onto the
lead-in section of the disc recording state information regarding
each set of data, the recording state information including
reproduction information indicating whether to inhibit
reproduction of any recorded encoded set of data; and
controller means for selectively masking an unnecessary
recorded encoded set of data by changing the reproduction
information to indicate inhibition of reproduction of such set of
recorded encoded data while retaining the information indicating
the order of recording, and for selectively cancelling the
masking of a masked recorded encoded set of data by changing the
reproduction information to indicate non-inhibition of
reproduction of such set of recorded encoded data while retaining
the information indicating the order of recording.
The examiner relies on the following references:
