Abstract
Disclosed is a head gimbal assembly for a hard disk drive that includes a head pivotally connected to a flexure. The flexure has a longitudinal axis. The assembly includes first and second micro-actuators that are located between the flexure and the head and spaced from the longitudinal axis. By way of example, the first and second micro-actuators may be thin piezo-electric transducers. Control signals can be provided to the micro-actuators to vary the pitch and/or roll of the head.
