Abstract: A magnetic head arm assembly (10) that supports suspensions (36,38,40,42) and head sliders (44) is formed as an integral die cast rigid structure having a pair of C-shaped side channels (12,141 extending from a thick base (56). Bridge elements (16,18) formed between the two channels support the head suspensions and sliders. Apertures (68) in the walls of the channels provide air flow for cooling, and serve to reduce mass thereby enabling faster access to data tracks.
