The variable capillary force arising between the surfaces of a slider and a textured magnetic disk is explored. Disk texture is modeled with an ensemble of bumps having geometries characteristic of laser-texture. Lubricant redistribution is modeled dynamically while elastic deformation of bumps is described by Hertzian contact models. The results demonstrate a significant impact of geometry on capillary spreading and on the subsequent net capillary force
