An actuator assembly for suspending and positioning at least one read/write head over at least one substantially flat surface of magnetic media is disclosed. The actuator assembly is comprised of at least one HSA and at least one actuator arm. Each actuator arm has an actuator arm distal end mating surface for coupling to at least one HSA and actuator arm upper and lower bearing mating surfaces for coupling to other actuator arms. Each HSA has an HSA proximal end mating surface for coupling to an actuator arm and an HSA distal end mating surface for coupling to a read/write head. At least one of the actuator arm distal end mating surfaces, HSA proximal end mating surfaces, actuator arm upper bearing mating surfaces, and actuator arm lower bearing mating surfaces is roughened to increase frictional coupling such that component alignment is not disturbed if the disk drive system is subjected to a mechanical shock. In addition, adhesive may be employed between the mating surfaces to increase coupling strength.
