Appeal No. 2000-1241
Application No. 08/424,156
BACKGROUND
Appellants' invention relates to an apparatus for recording and reproducing
digital picture data. An understanding of the invention can be derived from a reading of
exemplary claim 11, which is reproduced below.
1. An apparatus receiving an input digital picture signal and reducing
the data of the received input digital picture signal by a ratio of
approximately 1:9 so as to provide a recordable signal having a reduced
data bit rate for recording the reduced data bit rate signal, said apparatus
comprising:
a magnetic tape wound in a cassette and having a width of no
more than approximately 8 mm and a thickness of no more than
approximately 7 µm, said magnetic tape having a number of
predetermined characteristics including a residual magnetic flux density
value of approximately 4150 G so as to enable said reduced data bit rate
signal to be recorded thereon with a relatively high areal recording
density; and
means for recording said reduced data bit rate signal in successive
skewed tracks on said tape with said relatively high areal recording
density.
