Abstract
A data storage disc having an improved landing zone for supporting a head gimbal assembly for takeoff and landing. The improved landing zone having a landing surface formed of a patterned surface structure. The patterned surface structure including contact surfaces formed generally flush with a disc surface and depressions formed into the disc surface at predefined spaced location and extending below the disc surface. The patterned surface structure reducing stiction for "takeoff" of a slider from the disc surface and reducing interference of the slider and disc surface while flying over a transition zone at the edge of the data zone and landing zone.
