Abstract
An optical recording slider includes a slider body having a leading slider edge, a trailing slider edge and a center line extending from the leading slider edge to the trailing slider edge. The slider body carries an optical head along the center line. First and second longitudinal rails are positioned on the slider body. A third longitudinal rail is positioned on the slider body, between the first and second longitudinal rails and forward of the optical head. The third rail has a leading section, a waist section and a trailing rail edge. The leading section is rectangular and extends from the leading slider edge to the waist section. The waist section widens from a first width at the rectangular leading section to a maximum width of the third rail and then narrows from the maximum width toward the trailing rail edge. A recessed area extends from the leading slider edge to the trailing slider edge, between the first, second and third rails.
