Abstract
A high track density recording head assembly which eliminates cross-talk in high track density recording systems by positioning very thin neutralization heads between each pair of adjacent recording heads. The neutralization heads are provided with air gaps aligned with the gaps in the adjacent heads and have coils wound to develop a polarity opposite to that in the adjacent recording head. The neutralization head flux thus produced cancels the recording head lateral fringing flux that is responsible for recording interference in the adjacent recording tracks.
