the lead-in section of the disc to indicate inhibition or non-
inhibition of reproduction of sets of recorded encoded data.
The examiner argues [principal answer, page 7] that
since an unnecessary set of data is masked in Takahashi, but not
deleted, the recording order is kept unchanged even when the
unnecessary set of data is not to be reproduced. We agree with
this observation. However, that is no suggestion for the claimed
limitation of "retaining the information indicating the order of
recording" by the controller which selectively masks or unmasks
recorded encoded sets of data by changing the reproduction
information on the lead-in section of a disc to indicate
inhibition or non-inhibition of reproduction of such sets of
recorded encoded data.
With regard to Sako, the examiner admits [principal
brief, pages 4-5] that the control means in Sako does not
selectively mask and/or unmask unnecessary recorded data by
changing the reproduction information to indicate inhibition or
non-inhibition of reproduction of the recorded data as claimed.
Since Takahashi '116, as explained supra, also does not disclose
or suggest the controller functions, as claimed, the claimed
subject matter is not reached even if, somehow, the disc
