Abstract: A vertically-oriented servo track writer assembly and method for recording servo pattern on a disc surface includes a spindle hub assembly that rotates one or more discs in a substantially vertical plane and an actuator assembly that pivots an E-block about a substantially horizontal axis. The E-block includes one or more actuator arms and associated flexures, with each flexure including a servo recording head. Pivoting motion of the E-block moves each servo recording head in a substantially vertical plane adjacent a surface of an associated disc to record servo pattern information on the disc surface. The method further includes laterally moving the actuator assembly into and out of engagement with the spindle hub assembly to simplify loading and unloading discs from the spindle hub assembly.

Abstract: An actuator assembly and method for orienting a head over a disc within a multi-disc servo-track writer incorporates an actuator block, rotational air bearing, translational air bearing, adaptor plate, E-block and actuator arm/head assembly. Rotation of the E-block, and hence actuator arm/head assembly, is directly controlled by the movement of the rotational air bearing, which is rotated by a motor. The air bearing provides for reduced friction and, as a result, decreased eccentricity of the head as compared to related art configurations. A translational air bearing laterally positions the actuator assembly within the multi-disc servo-track writer for servo-track recording.

Abstract: Apparatus and method for orienting a head over a disc within a multi-disc servo-track writer preferably uses two gas bearings, an adaptor plate, and an actuator assembly including an E-block and arm/head assembly. Rotation of the E-block, and hence actuator arm/head assembly, can be controlled by the movement of a rotational gas bearing, which is rotated by a motor. The gas bearing provides for reduced friction and, as a result, decreased eccentricity of the head as compared to related art configurations. A translational gas bearing can be used for laterally positioning the actuator assembly for servo track recording.
