ABSTRACT:
A magnetic head according to one embodiment includes a first module having a flat profile tape bearing surface, a second module having a flat profile tape bearing surface, and a third module having a flat profile tape bearing surface. The third module is positioned on an opposite side of the second module than the first module. The tape bearing surfaces of the first, second and third modules may lie along substantially parallel planes, may be configured in a tangent (angled) configuration, or may be configured in an overwrap configuration. Data writing and reading functions are usually performed by different modules at a given time.
