ABSTRACT:
In a disk drive having a disk and a sampled track positioning servo system with a plurality of servo tracks spaced apart by a servo track pitch, a method and apparatus for separately determining the pitch of data tracks based on the servo track pitch and address fields located on the servo tracks. By separately optimizing data track pitch and servo track pitch, the design requirements for data density and servo control can be satisfied without the conflict imposed by a fixed relationship of the two track pitch dimensions.
