Abstract:
A magnetic head, according to one embodiment, includes a rowbar substrate having a tape support surface and a gap surface at a substrate edge. A closure is positioned opposite the gap surface of the rowbar substrate, the closure forming a portion of the tape support surface. A recessed gap region is interposed between the gap surface of the rowbar substrate and the closure, the recessed gap region having a recessed gap profile that extends between the gap surface of the rowbar substrate and the closure, the recessed gap region having a transducer row with at least one magnetic sensor on the gap surface of the rowbar substrate. An insulation layer is positioned over the recessed gap profile of the recessed gap region.
