Patent ID: 7653983

Claim:
A manufacturing assembly for manufacturing a disk drive, the disk drive comprising a base, a disk, a ramp near an outer periphery of the disk, a head coupled to a distal end of an actuator arm, wherein the actuator arm comprises a lift tab and the actuator arm is rotatable about a pivot, the manufacturing assembly comprising: a pre-merge arm comprising a contact surface for contacting the actuator arm; and a first actuator operable to actuate the pre-merge arm, wherein: when installing the actuator arm into the base of the disk drive, the actuator is operable to actuate the pre-merge arm in a first direction so that the contact surface biases the actuator arm rotationally about the pivot to bias the lift tab away from the ramp; and after installing the actuator arm into the base of the disk drive, the first actuator is operable to actuate the pre-merge arm in a second direction opposite the first direction so that the lift tab moves towards and contacts the ramp.
