摘要： A magnetic head includes a substrate having a first tape bearing surface and a second (outrigger) tape bearing surface, preferably with a slot therebetween. A plurality of elements (readers and/or writers) are coupled to the substrate and positioned towards the first tape bearing surface. The first and second tape bearing surfaces lie along planes, the planes being offset from one another spatially and/or angularly. The second tape bearing surface, like typical flat profile heads, induces a small spacing between a tape passing thereover and its tape bearing surface. The second tape bearing surface is positioned below the plane of the first tape bearing surface, thereby creating the proper wrap angle of the tape relative to the first tape bearing surface.
