Writing distinct servo patterns on individual transducers according to transducer read/write head characteristics in a data storage device

摘要

Distinct servo patterns are written on data storage media of a data storage device. Servo patterns of a first type are written for transducers of the data storage device having a first transducer characteristic. Servo patterns of a second type are written for transducers that do not have the transducer characteristic. The transducer characteristic can be a geometric criterion such as read head and write head track width, an operating characteristic such as frequency response, or otherwise. The first servo pattern may be a seamless untrimmed PES burst and the second servo pattern may be a seamed trimmed PES burst.
