Actuator including an actuator arm with a first microactuator supporting a read head and a force-balancing microactuator without any read head
An actuator assembly for use in a disk drive includes a first read head and a coarse actuator. The coarse actuator includes a coarse actuator body and a first actuator arm extending away from the coarse actuator body. The first actuator arm has a proximal end attached to the coarse actuator body and a distal end. The actuator assembly further includes a first microactuator attached to the distal end of the first actuator arm. The first microactuator supports the first read head. The actuator assembly further includes a first force-balancing microactuator attached to the distal end of the first actuator arm without any read head attached to the first force-balancing microactuator.
