Abstract: A head suspension assembly for supporting a read/write head of a disk drive located on a rotatable drive actuator arm is disclosed. The head suspension assembly includes a baseplate end proximate to and operatively connected to a first microactuator pair, the first microactuator pair communicatively coupled to a controller. The head suspension assembly also includes a load beam movably connecting the first microactuator pair to a second microactuator pair. The head suspension assembly also includes a head transducer end proximate to and operatively connected to the second microactuator pair, the second microactuator pair communicatively coupled to the controller. The read/write head is located proximate to the head transducer end, the read/write head being flexibly connected to the load beam, and the controller is configured to selectably transmit control signals to the first and second microactuator pairs in order to improve tracking control of the read/write head.

Abstract: A gimbal assembly includes a flex circuit with a first end extending along a loadbeam and second end having bond pads configured to be electrically coupled to a slider. The gimbal assembly includes a metallic layer with a fixed portion fixably attached to the loadbeam and a movable portion fixably attachable to the slider. The movable portion has at least one extension arm coupled to and providing support to the second end of the flex circuit. First and second linear actuators are coupled between the fixed portion and the movable portion. The first and second linear actuators cause a rotation of the slider in response to an electric signal.
