摘要： A monocoque head suspension carries a read-write head on a distal end and is attachable at a proximal end to an actuator assembly. The monocoque head suspension includes a bottom skin and a top skin, and also a core positioned between the bottom and top skins. The core has voids therein that form hollow regions between the bottom and top skins. The core may be made of low-density material, such as photo-imageable epoxy, polyamide or polyimide, deposited on the bottom skin, or may be a separately formed piece. The bottom skin and top skin may be made of a stainless steel material. The monocoque head suspension may be a component of an assembly to store data to a magnetic medium and read data from the medium.

摘要： An actuator load beam comprising a preload bend section defining an array of differently configured stiffness-reducing features. The stiffness-reducing features are characteristically sized in inverse relation to a respective distance from a longitudinal centerline of the actuator load beam at the preload bend section. An associated method comprising determining a thickness of a preload bend section for an actuator load beam associated with a desired resonant performance; determining a volume of stiffness-reducing features in the preload bend section associated with a desired vertical stiffness; and arranging an array of stiffness-reducing features associated with the determined volume in an array of sequentially smaller size with the largest size of the array being disposed nearest to a longitudinal centerline of the actuator load beam at the preload bend section.
