ABSTRACT:
A servo track writer assembly and method are provided for recording servo pattern information on a disc. The servo track writer assembly includes a spindle assembly, an actuator assembly and a servo recording head. The spindle assembly has a hub, which supports the disc and a spindle motor for rotating the hub. The actuator assembly has an actuator arm supported by an actuator bearing for positioning the actuator arm relative to the disc. At least one of the spindle motor and the actuator bearing has a gas-lubricated bearing with a working fluid, which includes helium. The servo recording head is supported by the actuator arm relative to the disc to record the servo pattern information on the disc as the spindle motor rotates the disc and the actuator bearing positions the actuator arm.
