An apparatus for etching optical servo tracks on a magnetic storage disk comprises optics for generating a beam of light for etching the servo tracks and a spindle for rotating the disk in proximity to the optics. The device further comprises a center pin at the center of rotation of the spindle and an alignment pin which is off-center of the spindle. A disk to be etched is placed on the spindle with the center pin through a center hole in the disk hub. A pressurized gas nozzle directs bursts of pressurized gas toward the edge of the disk to rotate the disk until an alignment hole in the disk hub engages the alignment pin.
