A suspended IO trace design for SSP cantilever Read/Write is described. Instead of having the whole I/O trace attached to surface of the cantilever, the cantilever is designed with fish-bone-like support and the I/O traces are anchored to cantilever structures 110 at some specific attachment locations with dielectric insulation in between. This design provides very compliant trace compared to cantilever's see-saw actuation around the torsional beam pivot and is also insensitive to residual stress variations from I/O trace in fabrication.
