Non operational shock resistance is achieved by preventing separation of the read/write head from the disk. Embodiments include optimizing the normal stiction force of a lubricant topcoat by controlling the texture geometry of the landing zone and lubricant topcoat thickness, particularly the density of protrusions. Laser textured landing zones having a protrusion density above about 4,500 protrusions/mm.sup.2 can provide an optimal normal stiction force in excess of 25 gf per interface and a lateral stiction force below 10 gf per interface.
