ABSTRACT:
In a multichannel head of the type wherein a plurality of transducers scan signal tracks of information across a magnetic tape within a system; and wherein each transducer includes a magnetic core having two pole pieces between which a gap is disposed while at least one turn of a conductor is magnetically coupled to the gap, the plurality of transducers are sequentially bonded together in an integral unit with their gaps disposed at essentially tandem locations.
