Abstract
A method and apparatus for generating servo information used in positioning the read head of a hard disk drive. The apparatus comprises a disk having a plurality of tracks, at least one of which has a data field which includes a plurality of servo bits, each of said servo bits being radially offset from an adjacent servo bit by a predetermined amount. In one embodiment, the predetermined amount is 5% of a width of the track. A servo signal based on the plurality of servo bits is generated and used to position the head relative to a track of the disk.
