ABSTRACT:
A head gimbal assembly includes an adaptive loading/unloading suspension with an aerodynamic compensation mechanism formed with or attached to the load beam. The compensation mechanism causes a variable and programmable dynamic gram load to be applied on the suspension such that a low gram load is achieved at the time of dynamic head loading, thus significantly minimizing or totally eliminating head-to-disk contact. The variable suspension gram load feature can be combined with an air slider bearing design to achieve optimal flying height performance and cost effectiveness. Such combination provides the air bearing design with an additional degree of freedom to achieve a more uniform flying height and improved altitude sensitivity than under a constant preload.
