Patent ID: 7561370

Claim:
A method comprising: obtaining a first repeated runout (RRO) correction value for a first servo seam on a storage medium by determining a written center line (WCL) value of the first servo seam indicative of radial deviation of the seam around a full circumference of the medium, and generating the first RRO correction value as an inverse of the WCL value, wherein a sum of the first RRO correction value and the WCL value provides a path along the first servo seam with substantially zero RRO to compensate for a radial offset between an actual position and a desired position of the first servo seam; determining a distance value indicative of a radial distance between the actual position of the first servo seam and an actual position of a second servo seam on the medium; and generating a second RRO correction value for the second servo seam to compensate for a radial offset between the actual position and a desired position for the second servo seam, the second error correction value determined in relation to the first error correction value and the radial distance value.
