Abstract
First and second nominal head-to-media spacings of a magnetic recording head are determined that result in tracks being written to a magnetic recording medium at respective narrower and wider tracks widths. Three or more adjacent tracks of user data are written to the magnetic recording medium using one of the first and second nominal head-to-media spacings so that the adjacent tracks alternate between the narrower and wider track widths.
