ABSTRACT:
There is provided a disk drive including a disk and an actuator. The actuator includes a first actuator arm. The first actuator arm has a region of reduced thickness between an arm longitudinal axis and a disk axis of rotation. An average thickness of the first actuator arm in the region of reduced thickness is less than an average thickness of the first actuator arm at an equal distance from an actuator axis of rotation but on an opposing side of the arm longitudinal axis. The actuator includes a suspension assembly having first and second flexible legs. The suspension assembly is coupled to the first actuator arm via the flexible legs. The second flexible leg is disposed further from the disk in a direction parallel to the disk axis of rotation than the first flexible leg and closer to the disk axis of rotation than the first flexible leg.
