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.

Abstract: An information handling system, such as a disc drive, including a base, a disc stack rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly also includes a load spring and a slider attached to said load spring. The slider for a disc drive includes a block of material having a leading edge, a trailing edge and an air-bearing surface. The air-bearing surface has at least one contact surface. Attached to the slider is at least one post for controlling the pitch of the slider. The post is movable between a first position and a second position. The post is attached to a piezoelectric element for moving the post between a first position and a second position. The post is actuated between the first position and the second position. In one embodiment of the invention, one post is attached to the trailing edge of the slider.
