Abstract: An electromagnetically controlled scanning magnetic transducer has two confronting magnetic core portions (21, 22) with poles defining a transducing gap (26). A control winding (38,39) is arranged in each core portion to provide a control flux therein. The control windings are arranged such that a steep magnetic permeability versus flux density characteristic across the transducer width is obtained. The control flux saturates a portion of each core at the transducer face adjacent to the gap. The saturated core portions define adjacent nonsaturated highly permeable core portions which overlap across the gap to obtain a transducing zone. The transducing zone can be altered, moved, scanned or otherwise positioned along the transducer width by electromagnetically controlling the saturated core portions.

Abstract: An improved method for electrically interconnecting a read/write head (36) to a flexure (14) having integral conductors (30). The flexure includes patterned electrical conductors which are exposed at an end of the flexure. A tooling fixture holds the head in alignment with a mounting region of the flexure such that a portion of each conductor extends beyond an end surface of the head. An ultrasonic probe tip (40) is used to bend each extending conductor portion and to press it into contact with a corresponding electrical bonding pad fabricated on an end surface of the head. The ultrasonic probe tip is energized to complete the electrical interconnection of each of the flexure's conductors to the read/write head.
