An integrated lead suspension (ILS) or flexure has a connection scheme that allows for coplanar and interleaved conductive traces between read/write circuitry and a read/write head in a magnetic recording disk drive. At each end of the flexure there is an island of electrically conductive substrate material with vias in an insulator layer that permit electrical connection to the islands. Conductive traces on the insulator layer are grouped into two sets and extend generally parallel along the length of the flexure, with the traces from one set being interleaved with traces from the other set and each set carrying one of the positive or negative signals. At each of the ends, all of the traces from a set are connected through the vias to the island at that end.
