A method for correcting a track pitch error in servo tracks written on a
magnetic recording media coupled with a disk surface, by using a
subsequent servo-write pass, comprises propagating servo tracks across
the magnetic recording media in a previous servo-write pass. The servo
tracks have radial positioning servo code. The servo tracks enable a
magnetic transducer to be positioned to at least one radial position on
the magnetic recording media. At least one corrected radial reference
point is calculated for the track pitch error written on the magnetic
recording media, by identifying at least one inconsistency between a
mechanical response of an actuator and the track pitch. A corrected
location for at least one servo track is identified. At least one new
servo track at the corrected location is propagated with the subsequent
servo-write pass. Optimum data track distribution across the disk surface
and optimum reading and writing of data to and from the magnetic
recording media is enabled.
