A method of writing data to multiple disks on a servo track writing machine comprises the steps of providing a cylindrical disk stacking tool comprising a base and a spindle, loading a first disk onto the spindle in alignment with the base, loading a second disk onto said spindle in alignment with the first disk, placing the loaded disk stacking tool on the servo track writing machine, and simultaneously writing data to the disks with the servo track writing machine. As many disks as desired may be so written to. The disk stacking tool further includes a clamp for locking the disks in place.
