Patent ID: 7440234

Claim:
A disk drive comprising: a disk drive base; a disk rotatably coupled to the disk drive base about a disk axis of rotation; and an actuator rotatably coupled to the disk drive base about an actuator axis of rotation, the actuator including: a first actuator arm defining an arm longitudinal axis extending from the actuator axis of rotation, the first actuator arm having a region of reduced thickness disposed between the arm longitudinal axis and the disk axis of rotation, an average thickness of the first actuator arm in the region of reduced thickness being less than an average thickness of the first actuator arm at an equal distance from the actuator axis of rotation but on an opposing side of the arm longitudinal axis; and a first suspension assembly having first and second flexible legs, the first suspension assembly coupled to the first actuator arm via the first and second flexible legs, the second flexible leg being disposed closer to 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.
