Abstract

A head load/unload tool for use in disk file assembly enables the head suspensions, projecting from the head arm stack, to be spread apart to enable them to be merged with the disk stack and subsequently released to allow the heads to contact the disks. Essentially, the tool includes a split shaft, each half of which is provided with orthogonally projecting load bails for engaging the head suspensions. Each half shaft also includes a stub pin which locates in a respective inclined slot in a surrounding sleeve. Rotation of the sleeve causes opposite longitudinal displacement of the half shafts to spread or close the bails, thus unloading or loading the (Image Omitted) heads. Further rotation of the sleeve removes the bails from the head/ arm stack. The principle is best illustrated in Fig.
