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： The invention operates two control paths. The micro-actuator control stimulates the micro-actuator. The voice coil motor control path includes the voice coil motor control generating a voice coil control signal, notch filtered to remove at least one significant excitation resonance for a notch filtered voice coil control signal. Amplifying the notch filtered voice coil control signal by a tuning gain stimulates the voice coil motor. A decoupling feedback filter uses the micro-actuator control signal to create a decoupling feedback signal used to decouple the two control paths. A track following command, with PES removed, directs the micro-actuator control. The voice coil motor control is directed by the track following command, with both PES and decoupling feedback signal removed. Preferably, the servo-controller digitally supports the elements of the invention. Implementing the method may preferably include the servo-controller program system residing in an accessibly coupled memory. The invention includes optimizing an implementation within the hard disk drive. The optimization may be part of the manufacturing process for the hard disk drive. The invention includes the hard disk drive as the product of that manufacturing process.
