摘要： Head stack assembly coupling at least two micro-actuators sharing lateral control signal. Any two adjacent micro-actuators respond to lateral control signal by opposite lateral directions. With pairs of micro-actuators, lateral motion of the micro-actuators will be cancelled, essentially leaving head stack assembly without induced torque. With odd numbers of micro-actuators, head stack assembly will effectively experience only lateral motion of one micro-actuator, minimizing induced torque. The micro-actuators may use electrostatic effect and/or piezoelectric effect to create lateral motion. The micro-actuators may further include a vertical actuation capability, which may preferably be independent of the lateral control signal. The servo controller operates based upon micro-actuator being used. Embedded circuit includes servo controller. The hard disk drive containing head stack assembly and further containing servo controller. Manufacturing hard disk drive and head stack assembly. The head stack assembly and hard disk drive, as products of these manufacturing processes.

摘要： A method and its implementation as a program system are disclosed herein for generating an air flow report based upon a cellular model of the air flow of a hard disk drive including a parameterized component approximated by a component parameter list and a map of the partitioned regions of the hard disk drive. The air flow report is generated based upon the cellular model and a partition/region map. The partition/region map lumps the simulation domain into a small number of regions and then calculates the fluxes across boundaries of the regions. These fluxes accumulate the results of many individual cells, averaging out small variations caused by rounding and/or the convergence properties of the specific cellular approach used. A simulation figure of merit is calculated from the air flow report that further refines the accuracy, effectively removing even more noise.

摘要： Head gimbal assembly (HGA) may include a piezo layer mechanically coupled with the slider or include a piezo element mechanically coupled by the flexure to the slider top near the read-write head. A bridge flex circuit is included, providing a piezo-control bundle to at least one piezo layer lead.

HGA may include a micro-actuator to position read-write head near track on accessed, rotating disk surface. Flex circuit assembly may provide a source control bundle, shared with the micro-actuator control bundles for multiple read-write heads. When accessing, all micro-actuators perform same positioning action, insuring proper positioning of read-write head. This applies to both co-located and non co-located micro-actuators. Wire bundles may include one or two active signal wires. Voice coil actuators and hard disk drives, and their manufacture, are included.
