ABSTRACT:
In a medium having data fields and servo fields, a dual servo format includes a plurality of large and small servo fields for determining the position of a transducer over the medium. The large servo fields have a circumferential length that is larger than the circumferential length of the small servo fields. Both types of servo fields are distributed across the medium among the data fields.
