ABSTRACT:
In a segmented helical-scan recorder-playback arrangement, alternate scans of the heads across the tape transduce information relating to the top and bottom of the raster. Noise bands and raster distortion occurring during the crossover of a scanning head from track to track during playback in a stop or variable-speed mode is prevented by playback heads having gaps wider than the width of the recorded track and by azimuth separation between adjacent tracks.
