Abstract
Methods and apparatus are provided for creating servo-tracks on the R-side of single-sided hard memory disks. The method includes placing two single-sided disks in a concentric contact merge orientation with the R-side of each disk facing outwardly. Two independent servo-track writers then position an independent transducer proximate each R-side and write desired servo-track data to the R-side surface of each disk. The disks are de-merged and either disk may be placed in any single-sided disk drive.
