A system for adjusting the gram load, static attitude roll and radius geometry of a suspension with a high degree of accuracy and repeatability includes a clamp, load-engaging member, actuator, laser and control system. The mounting region of the suspension to be adjusted is releasably received and clamped by a clamp. A load beam of the suspension is engaged and supported at adjust positions with respect to the clamp by the load beam-engaging member. The load beam-engaging member is driven and positioned by the actuator. IR light from the laser is directed to the spring region of the suspension by optical fibers. The control system includes a pre-adjust input terminal, memory and a controller. Information representatives of a measured pre-adjust fly height gram load, static attitude roll and radius geometry values of the suspension are received at the pre-adjust input terminal. Adjust data representative of load beam adjust positions which will cause the suspension to have a desired post-adjust fly height gram load, static attitude roll and radius geometry values after the load beam is stressed relieved is stored in the memory. The controller is coupled to the pre-adjust input terminal, actuator, laser and memory, and controls the system by: 1) accessing the memory as a function of the measured pre-adjust fly height gram load, static attitude roll and radius geometry values to determine the load beam adjust position which will cause the suspension to have the desired fly height gram load, roll and radius geometry values after the load beam is stressed relieved, 2) actuating the actuator and causing the load beam-engaging member to position the load beam at the adjust position, 3) actuating the laser to stress relieve the spring region of the load beam while the load beam is positioned at the adjust position, and 4) actuating the actuator and causing the load beam-engaging member to release the load beam after the load beam is stress relieved.
