Abstract
A method and apparatus is described for gradually transitioning a slider from operation over a patterned data zone to landing on a patterned CSS zone. The ratio of raised area width to recessed area width of a pattern in a transition zone and/or CSS zone may be varied across the radial dimension of the disk. By changing the ratio of raised area width to recessed area width of the pattern in the transition from slider operation over the data zone to landing in the CSS zone, it is possible to gradually change the height of the slider from flying to non-flying conditions.
