摘要： A magnetic head follows a track in a hard disk drive as positioned by micro-actuator and voice coil motor. Embodiments operate two control paths. The micro-actuator control path generates a version of micro-actuator control signal stimulating the micro-actuator. The voice coil motor control path generates a version of voice coil control signal, amplified based upon tuning gain to stimulate voice coil motor. A decoupling feedback filter decouples these control paths, using the micro-actuator control signal version. Either control path may include a notch filter. A track following command, with PES removed, directs the micro-actuator control. The servo-controller may digitally support the invention, which may include the servo-controller program system. An implementation may be optimized within a hard disk drive, possibly as part of the manufacturing process. The hard disk drive is a product of that process.

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.

摘要： The invention includes a D33 mode piezoelectric actuator region, including electrodes of differing length to produce a bending motion. The invention also includes a piezoelectric actuator containing a first piezoelectric actuator region coupled to a second piezoelectric actuator region, which may be separated by the ceramic material. Applying a first potential difference between electrodes generates a first bending of the piezoelectric actuator region. Applying the negative first potential difference generates the complement first bending for the piezoelectric actuator. The piezoelectric actuator region may be used to radially move a coupled transducer by the first bending. The piezoelectric actuator may be used to radially move a coupled transducer by the first bending and/or its complement. The invention includes the methods of making the piezoelectric actuator region and the piezoelectric actuator, and their products.
