ABSTRACT:
The present invention provides a computer directed head stack assembly installation system with an installation software stored on recordable media directing the controlling a sequence of head stack installation assembly steps executed by a robotic assembly to pick and place a head stack assembly into a basedeck. The installation software program monitors compliance of the placement operation regarding mechanical resistance encountered by the head stack assembly engaging the basedeck compared to a dynamic force threshold F determined by the equation [F=(f(p)+/−x)] and against the dynamic slope V determined by the equation [V=V=(fn−fn−1)/(pn−pn−1). Upon successful installation of the head stack assembly into the basedeck forming the head disc assembly, the head disc assembly is released from the head stack assembly installation station.
