    Abstract: An assembly for lapping multiple row bars, the assembly including a carrier having at least one carrier bond pad, multiple row bars adjacent to each other in a stack, wherein a first row bar of the stack is positioned closer to the carrier than any of the other multiple row bars of the stack and comprises at least one row bar bond pad, an electrical connection between at least one of the carrier bond pads and at least one of the row bar bond pads of the first row bar, and at least one electrical trace extending through at least two of the multiple row bars and electrically connected to at least the first row bar and one additional row bar of the stack. An outermost row bar of the stack includes an outer surface and at least one electronic lapping guide.

    IPC: G11B5/60

    CPC classification number: G11B5/6082

    Abstract: Sliders that include a slider body having an outer side edge, an inner side edge, a trailing edge and a leading edge, and a base; a trailing edge set of features positioned towards the trailing edge of the slider body, the trailing edge set of features having air bearing surfaces, the air bearing surfaces being above the base of the slider body; a leading edge set of features positioned towards the leading edge of the slider body; a gap positioned between the trailing edge set of features and the leading edge set of features, the gap having a gap surface, the gap surface substantially coplanar with the base of the slider body; and a first gap feature and a second gap feature distributed evenly within the gap from the inner side edge to the outer side edge, the first and second gap features each having upper surfaces, the upper surfaces of the first and second gap features being above the base of the slider body but below the air bearing surface of the trailing edge features.

    Abstract: A method of lapping multiple row bars provided in a stack, including the steps of electrically connecting at least one row bar bond pad of a first row bar to at least one carrier bond pad of a carrier, electrically connecting an outermost row bar of the stack to the first row bar of the stack by at least one electrical trace, wherein the outermost row bar comprises at least one electronic lapping guide, lapping an outer surface of the outermost row bar until a signal provided by the at least one electronic lapping guide of the outermost row bar reaches a predetermined value, terminating the lapping of the outermost row bar, and removing the outermost row bar from the stack to expose a second row bar, wherein the second row bar is electrically connected to the first row bar with the at least one electrical trace.
