Operating micro-actuator using stroke sensitivity estimate including controlling micro-actuator directing read-write head toward track using stroke sensitivity to create micro-actuator stimulus signal. Servo controller may support operating micro-actuator. Method of estimating may be used to create stroke sensitivity during at least initialization/calibration of manufacturing hard disk drive. Embedded circuit may include servo controller. Hard disk drive may include servo controller, possibly embedded circuit, coupled to voice coil motor, to provide micro-actuator stimulus signal driving micro-actuator. Invention includes making servo controller, possibly embedded circuit, and/or hard disk drive. Servo controller, embedded circuit, and hard disk drive are products of these processes.
