Dual actuator pivot bearing system and method for making the same

A disk drive, comprising:

• at least one rotatable disk;
• at least first and second separately movable heads for providing transducing action with respect to the disk;
• first and second head actuators, wherein the first head actuator provides radial movement of said first head relative to said disk and said second actuator provides radial movement of said second head relative to said disk, the radial movement provided by each actuator being separately controllable from that of the other actuator;
• a dual actuator pivot for mounting the first and second actuators, the dual actuator pivot further comprising a first and a second actuator bearing assembly each having a sleeve and at least one bearing press fitted together, the first and second actuator bearing assemblies are press fitted to a shaft for rotatably securing the first and second head actuators respectively, wherein the first and a second actuator bearing assemblies further comprise an upper and lower ball bearing press fitted into a top and bottom bore of an upper sleeve respectively to form the first actuator bearing assembly and a lower sleeve having an upper ball bearing press fitted into a top bore of the lower sleeve to form the second actuator bearing assembly, the first and second actuator bearing assemblies being press fitted to the shaft assembly comprising the shaft having a ball bearing press fitted at a shaft base;
• and
• at least one controller, operatively coupled to the first and second head actuators for controlling the movement of the first and second head actuators about the dual actuator pivot, the at least one controller producing control signals to control the movement of the first and second actuators.
