Classification: G11B,H04N

Abstract:
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 &mgr;m, 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, in which said reduced data bit rate signal is recorded with a minimum wavelength of 0.5 &mgr;m.
