ABSTRACT:
An apparatus and method for automatically adjusting the gram load and static attitude in a head suspension assembly comprising one or more lasers, a fiber optic switch, a measurement apparatus and a computer control means. The fiber optic switch includes a plurality of fiber optic lines which direct the output of the laser to well-defined regions on the suspensions in a disk drive. Irradiation of the suspension by the laser causes a load change which alters the static attitude change in the slider. In the method of the present invention, the initial gram load or static attitude is measured by the measurement apparatus and the control means calculates how much energy is required to cause the change needed to achieve the desired condition. Other information, such as the type of laser to be used is also specified by the control means. The laser then delivers output to the suspension through the fiber optic line having an angled end and the static attitude or gram load is remeasured to determine if additional adjustment is required.
