ABSTRACT:
A method of recording and reproducing a video signal with respect to a magnetic tape includes the steps of converting the video signal into digital form; distributing the digitized video signal to a plurality of channels; simultaneously recording the digitized video signal in eight parallel tracks extending obliquely on the tape without guard bands therebetween and with the digitized video signal in alternate ones of the tracks being recorded with a first azimuth angle and the digitized video signal in the remaining tracks being recorded with a second different azimuth angle; reproducing the digitized video signal from the eight parallel tracks; grouping the reproduced digitized video signal into two groups, one group including only those portions of the reproduced digitized video signal that were recorded with the first azimuth angle, and the other group including only those portions of the reproduced digitized video signal that were recorded with the second azimuth angle; and processing the reproduced digitized video signal separately for each group. Apparatus for performing the above method is also provided.
