Abstract:
A servo track writer assembly for recording servo pattern information on a disc comprising:a spindle hub assembly having a hub supporting the disc in a substantially vertical plane and a motor for rotating the hub and the supported disc at a predetermined rate about a horizontal axis; an actuator assembly having an E-block and a motor for rotating the E-block about another substantially horizontal axis, the E-block supporting an actuator arm and a flexure extending from a distal end of the actuator arm in a substantially vertical plane; and a servo recording head mounted to a distal end of the flexure, wherein the servo recording head moves in a substantially vertical plane along an arcuate path adjacent a surface of the disc to record the servo pattern information on the disc surface as the spindle hub assembly rotates the disc and the actuator assembly rotates the E-block.
