Abstract
Methods and devices are described that provide improved electromagnetic interference (EMI) protection for suspension assemblies. In one embodiment, a ground line is provided among the traces that are used in the suspension. Alternatively, a top ground plane is provided on top of the conductive traces with an interposed insulative layer. The ground line and/or the top ground plane provide EMI protection for read and write signals traveling through the traces (e.g., read and write traces) of the suspension assembly. The ground line and/or the top ground plane reduce the interaction between the read and the write traces, thus minimizing cross talk.
