摘要： 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.

摘要： An information handling system, such as a disk drive, including a base, a disk 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 and load spring are attached to form a gimballing connection between the slider and the load spring. The slider includes an air-bearing surface which has a contact area. The slider also includes a transducer. The transducer is typically located near said contact area. The contact area includes a roughened surface portion and a smooth surface portion. The smooth surface portion is adjacent the transducer. The roughened surface portion is rougher than the smooth surface portion. The roughened surface portion is also rougher than the other surfaces associated with the air-bearing surface of the slider. The roughened surface portion of the contact area is formed by one of several techniques. One of the techniques uses a wet etch to remove at least one of the phases of a multi-phase material. Another technique defines the area to be roughened using photolithography. After exposing the photoresist using either a mask or a laser, a portion of photoresist is removed and the areas unprotected by photoresist are dry etched to form the roughened contact area.

摘要： A disk drive system includes a base, a disk rotatably attached to the base, and an actuator assembly movably attached to the base. A ramp for loading and unloading a transducing element to and from the disk is also attached to the base. The ramp has an inclined surface and a flat surface that has a lower coefficient of friction than the surface associated with a parking detente. This is accomplished by molding features into the inclined surface and the flat surface and leaving the surface associated with the parking detent substantially smooth or featureless. This can also be accomplished using a molding process in which two materials are used. A first material will produce a coefficient of friction which is higher than the second material.
