Abstract
A data transducer head mounting structure for a height compacted, low power head and disk assembly of a fixed disk data storage subsystem has an elongated load beam including a head arm attachment end region for attachment to an outward end of an actuator head arm; a leaf spring loading region; flexure attachment region for attachment of a gimbal flexure for mounting a transducer head; a dynamic loading tab formed at the outermost part of the head end region beyond the transducer head; and, a load beam region located between the leaf spring loading region and the dynamic loading tab. In one aspect of the invention a loading ramp structure is positioned adjacent to a peripheral edge of the storage disk and cooperates with the dynamic loading tab. In one independent aspect of the present invention, the load beam region includes two L-shaped flanges facing toward an adjacent data storage surface, and a trussing structure is attached to the outer surfaces of the flanges to enclose the load beam region. In a further aspect, the leaf spring loading region including two parallel outer segments defining a central longitudinal opening which are dimensioned to tune torsional mode resonances …
