Abstract:
A magnetic tape head assembly for use with a magnetic recording tape passing thereover, the assembly comprising:a first module and a second module attached to each other, the first module comprising: a first wafer chip comprising a first thin film transducer element; a first cover bar bonded to an outer surface of the first wafer chip; and a first contour forming tape facing surfaces of the first wafer chip and the first cover bar, the first contour comprising an element bump around the first thin film transducer element, a pair of first grooves with one first groove being located on each side of the element bump, and a pair of first outriggers with one first outrigger being adjacent to each of the first grooves; the second module comprising: a second wafer chip comprising a second thin film transducer element; a second cover bar bonded to an outer surface of the second wafer chip; and a second contour forming tape facing surfaces of the second wafer chip and the second cover bar, the second contour comprising an element bump around the second thin film transducer element, a pair of second grooves with one second groove being located on each side of the element bump, and a pair of second outriggers with one second outrigger being adjacent to each of the second grooves; wherein: the first and second modules are bonded together in a back-to-back arrangement at inner surfaces thereof, the first and second contours form a substantially contiguous working contour for the assembly, in the bonded arrangement, and the contiguous working contour comprises a central groove substantially at a location where the first and second modules are bonded together.
