摘要
A micro-milliactuator, a micro-microactuator, an actuator arm assembly, a hard disk drive and a method for operation of the hard disk are provided. In accordance with one aspect, the actuator arm assembly includes an arm, a slider for reading and writing information to disk media in response to read/write signals, and an actuator selected from the group comprising a micro-milliactuator and a micro-microactuator. The actuator has the slider mounted thereon and supports it above the disk media. The actuator includes one or more piezoelectric actuators for horizontally shifting the slider in response to actuator control signals. The actuator further includes one or more sensors physically coupled thereto for vibration sensing, compensation and suppression, the one or more sensors generating sensor signals in response to sensed vibrations during operation, wherein the actuator control signals are generated at least partially in response to the sensor signals.
