Abstract
An apparatus includes a first read/write head coupled to a first micro actuator, a second read/write head coupled to a second micro actuator, an actuator and a controller. The actuator is coupled to both the first and second micro actuators. The controller is configured to position the first read/write head in response to a first micro actuator control signal and an actuator control signal. Further, the controller is configured to position the second read/write head in response to a second micro actuator control signal and the actuator control signal. The positioning of the first and second read/write heads by the controller is performed substantially simultaneously.
