Abstract
In using helical-scan-type apparatus for recording video information in parallel tracks on magnetic tape, the typical slanted arrangement of the tracks results in track-to-track shifting or offset. Tape scanning apparatus adapted for implementing an improved recording technique employs an incremented scanning head speed for scanning one track in a period of time that departs from the period of one video signal sequence (e.g. a video field or frame) by an amount that is specially selected in accordance with the track offset. By so incrementing the scanning head speed the position of a video signal sequence within a track is shifted with respect to the signal sequences in adjacent tracks in a manner that compensates for the offset and provides a closer correlation between the video signal in adjacent tracks, thereby minimizing the effects of cross-talk between tracks.
