Abstract
A disc drive includes a base and a disc rotatably attached to the base. The disc drive also includes an actuator assembly rotatably attached to said base and a device for moving the actuator assembly. The actuator assembly carries a slider. A slider for a disc drive adapted to interface with the surface of the disc. The surface of the disc is provided with an overcoat having a specific hardness. The slider has a leading edge, a trailing edge, and an air bearing surface positioned between the leading edge and the trailing edge. The slider includes a plurality of slider integrated pads, at least some of the slider integrated pads having a hardness which is greater than the hardness of the disc surface. All the slider integrated pads may be harder than the hardness of the disc surface or at least a group of slider integrated pads located near the trailing edge of the slider are harder than the hardness of the disc surface.
