Abstract:
A laser servowriting system for providing a servo pattern on a magnetic data storage disk, the system comprising:a linear guide;an optics sled including laser optics, the optics sled mounted on the linear guide for translational movement, wherein the center of mass of the optics sled moves along a centroidal axis as the optics sled moves along the linear guide;three or more actuators operatively connected to the optics sled, wherein the actuators move the optics sled along the linear guide, and further wherein the centroidal axis is located within a closed geometric figure formed on a reference plane perpendicular to the centroidal axis by the actuators;a laser source directing laser energy at the laser optics on the optics sled; anda rotation system for rotating a magnetic data storage disk during servowriting of an optical stitch pattern thereon.
