Apparatus for recording and reproducing digital picture data. |
摘要 |
<p>In an apparatus for recording and reproducing a digital picture signal, the large number of data bits in the digital picture signal to be recorded is reduced by a ratio of approximately 1 : 9, and the thus compressed data are recorded with a recording density of at least approximately 0.8 bit/ mu m<2> in relatively narrow successive skewed tracks (TA, TB) without guard bands on a metal evaporated magnetic tape (78) having predefined characteristics. The magnetic tape (78) has a width of no more than approximately 8 mm and a thickness of no more than approximately 7 mu m and is wound in a relatively small size cassette (115, 211). <IMAGE></p> |
