A magnetic head suspension assembly and method are designed to include a substantially inflexible support arm mounted at one end to an actuator motor in a data storage disk drive system. At the opposite end of the support arm is a gimbal. An air bearing slider having at least one read/write head is connected to the gimbal. The gimbal is adapted to accommodate pitch and roll motion and is compliant in the direction perpendicular to a surface of the data storage medium to be read. The gimbal is parallel-coupled with a load spring that is connected to the support arm to apply a load force. This arrangement improves the shock-resistance characteristics of the suspension assembly, since the support arm does not add to the inertial force caused by accelerations from shock events. In a preferred embodiment, the electrical connection to the read/write head is via electrical traces that are printed onto the support arm and gimbal. Traces are also formed on the gimbal springs to extend to a solder-reflow location at an interface to the slider.
