Abstract
A disk drive rotary actuator with a rocking pivot allowing limited angular rotation of an actuator arm assembly. A surface (34) fixed to the arm 16 rocks on fixed surface (32) held in contact by a spring (50). Second rocking surfaces are also provided on the rotational axis. A flexure leaf (40) connects the arm (16) to the disk drive base to provide positional stability. The rocking pivot actuator has advantages of simplicity, and improved frictional characteristics. A flexible circuit connection may pass through the pivot.
