Abstract
A method of manufacturing a disk drive is disclosed in which servo information is written in tracks on a disk surface, the track width performance of the associated read/write transducer is measured, the track width performance is analyzed and a data track pitch is established. Based on the established track pitch, a track location formula for data tracks on the disk surface is defined. For a disk drive having a plurality of read/write transducers, a track location formula is established for each transducer. A method for measuring track width performance of a read/write head is also disclosed.
