Abstract
A hard disk drive has actuator arms with a load beam or suspension extending from one end. Each suspension carries an integrated lead layer with electrical traces which are connected to a magnetic read/write heads for interacting with magnetic disks in the disk drive. Each suspension also has a pair of polymer pads on each side of the traces. Each pad has a series of bumps which give the pads a greater thickness than the lead layer for preventing contact between the traces, suspensions and magnetic disks during shock vibration. The pads also prevent contact between the trace conductors and the head separator during the separation process.
