  • Pivot bearing assembly for compensating for disk drive actuator tilt
    Patent number: 6687092
    Abstract: A disk drive pivot assembly design has a shaft that supports two actuators. The pivot assembly design compensates for the tilting of the actuators due to shaft bending during seek operations. Two types of bearings of differing stiffness are used to achieve improved performance. The axially innermost bearings are stiffer than the axially outermost bearings, which are relatively compliant. By having two different bearing stiffnesses, the boundary conditions of the pivot assembly are adjustable and can compensate for shaft bending, which is greatest near the center of the pivot assembly.
