APPARATUS FOR RECORDING AND REPRODUCING DIGITAL PICTURE DATA |
摘要 |
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.m2 in relatively narrow successive skewed tracks without guard bands on a metal evaporated magnetic tape having predefined characteristics. The magnetic tape 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.
