Abstract: Magnetic transducing heads are disclosed which include two stacks of ferromagnetic laminations. Each lamination in one stack is paired with a lamination in the other stack. At their closest point each pair of laminations defines a transducing gap. The stacks are so positioned that the transducing gaps form a linear array. The tops of the two stacks of laminations are so configured as to lie in a common cylindrical surface, the axis of the common cylindrical surface being perpendicular to the rectilinear array of transducing gaps, though not intersecting it. A cylindrical rotor is rotatably mounted so that its surface is very close to the cylindrical top surfaces of the two stacks. Four low reluctance bridging elements are mounted in the rotor and at or near its cylindrical surface. An exciting winding surrounds one stack of laminations.
