  • Head stack assembly gramload process capability improvement
    Patent number: 7698085
    Abstract: A method for measuring a gramload corresponding to a read/write head, where the head is an inner head of a plurality of heads in a head stack assembly (HSA), involves a measurement instrument having a plurality of cam-rods for systematically placing each of various heads in a preloaded state in order to measure the respective gramload of the heads. While an inner head's gramload is being measured, an adjacent inner head is configured in a supported state, and the cam-rod corresponding to the supported head transmits some additional force to the head whose gramload is being measured, e.g., via a common support arm for the adjacent inner heads. Therefore, this additional applied force is compensated for in order to provide more accurate gramload values.
