Abstract
An apparatus includes a controller configured to be coupled to a read/write head. The controller is configured to perform various operations including detecting a change in a time interval difference between servo sectors of a servo marked recording medium, converting the change to an offset signal that compensates for the change, and positioning the read/write head relative to the servo mark recording medium in response to the offset signal. The change in the time interval difference is representative of disk slip.
