Abstract: An injector head adapter can include a frame member adapted to couple to an injector head table, an opening in the frame member, a plurality of locator arms coupled to the frame member, each locator arm having a slot, a plurality of pins comprising a pin engaged with the slot of each locator arm, and a plurality of lock nuts comprising a lock nut coupled with each of the plurality of pins. A pin can be adapted to couple to a slot at one or more locations relative to the opening. An injector head system can include an injector head platform, an injector head table, which can be movable, and an injector head adapter.

Abstract: An electric motor for a magnetic disk memory device includes a conical hub and a conical plane or grooved base and an integral air-bearing which significantly reduces non-repeatable runout, audible noise, and vibration. The base is rigidly attached to the shaft while the hub, which carries all of the load, rotates on the air cushion created by a pressurized air film. An upper sleeve controls the pressure fluctuation in the air film in a dynamic condition. In a static condition, the hub rests on a dry lubricated surface. The force developed due to the pressurized air film balances the rotating member in any condition.
