摘要:
A slider body configuration, or slider, for carrying a data transducer in cooperative relationship with a rotating data storage disc. The slider includes a plurality of landing pads which serve to minimize the contact area between the slider and the discs when the heads are parked in contact with the discs, and the landing pads project from surfaces which are farther removed from the disc surface than the air bearing surfaces, thus minimizing the size and strength of any liquid miniscus formed between the slider and the disc when the slider and disc are in contact. By recessing the bases of the landing pads from the air bearing surfaces, the effect of the landing pads on the separation between the data transducer and the discs is minimized.

An air bearing slider for a disc drive has an overcoat localized on the air bearing surface to provide a continuous covering over a leading portion of the air bearing surface. The overcoat terminates in a trailing cut-off line, and a trailing portion of the air bearing surface is not covered by overcoat. The overcoat also covers the pole tips of the transducer at a pole tip recession from the air bearing surface. The leading portion covered by the overcoat includes all of the air bearing surface that contacts the disc during contact/start/stop, which is protected by a uniform continuous overcoat layer. The trailing cut-off line is disposed at an angle to expose the trailing corners of the air bearing surface, such that all of the overcoat is elevated above the lowermost portion of the air bearing surface through pitch and roll angles of flying at inner and outer radii. Methods of applying the localized overcoat include subtractive and additive photolithographic deposition processes. The overcoat over the pole tips protects the pole tips during subsequent processing steps of forming the slider cavity.

An asperity sensing head is used for detecting asperities on the surface of a disc while the disc is rotated. The asperity sensing head includes a slider body having a first rail and an air bearing surface. A first asperity sensor is carried by the slider body in the first rail. A second asperity sensor is also carried by the slider body in the first rail wherein the first and second asperity sensors are separated by a groove in the first rail.

A mounting system attaches head suspensions to actuator head mounting arms of a disc drive actuator. The mounting system includes head suspension mounting plates and features on both the head suspension mounting plates and on the actuator head mounting arms that facilitate snap-fitting or press-fitting of the mating components, as well as features that ensure both accurate alignment and maintenance of the position of the mounted head suspensions in and about the major orthogonal axes.
摘要:
A slider with contact interface features for contact starts and stops. Contact interface features include elevated leading edge contact interface features including elevated contact pads, ribs or protective layer. In addition, the invention includes a slider with a trailing edge contact interface at the bearing surface having a relatively rough surface structure including textured or rough surface patterns.

摘要:
A method of making an abrasive article including the step of preparing a master plate with a surface having a shape. Depositing a spacer layer on the surface of the master plate. A slurry containing an adhesive and abrasive particles is deposited on a surface of the spacer layer. A substrate embedded with abrasive particles having a surface generally complementary to the surface of the master plate is fabricated. A spacer layer is formed by various method controlled the height of the protruded abrasive particles. The master plate and the spacer layer are separated from the substrate to expose abrasive particle protruding a substantially uniform height. An abrasive article made according to this method is also disclosed.
