  • Magnetic head arm assembly
    Patent number: 4443824
    Abstract: A magnetic head arm that supports suspensions and head sliders is formed as an integral die cast rigid structure having two coextensive C-shaped channels along the sides terminating in a thick base. Bridge elements formed between the two channels support the head suspensions and sliders. Apertures in the walls of the channels provide air flow for cooling, and serve to reduce mass thereby enabling faster access to data tracks.
