Abstract: A slider of a magnetic recording head comprises a media-facing surface, an upper surface opposing the media-facing surface, a leading edge, and a trailing edge. A plurality of electrical bond pads is disposed in a spaced-apart relationship on the trailing edge of the slider. An interconnect interposer is connected to the trailing edge of the slider. The interposer comprises a back side comprising a plurality of electrical contacts in contact with the plurality of bond pads on the trailing edge of the slider. The interposer also comprises a front side comprising a plurality of electrical interposer pads corresponding in number to the plurality of electrical contacts on the back side. The interposer further comprises a plurality of conductors each of which electrically couples one of the plurality of electrical contacts on the back side with one of the plurality of interposer pads on the front side.
