摘要： A disc drive, includes 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 bearing housing, head mounting arms, head suspensions attached to the head mounting arms and a head assembly attached to the head suspension. The disc drive also includes a hub having a cylindrical body. The hub includes a disc mounting flange on one end of the hub. A disc has an opening therein sufficient to allow the hub to fit within the opening of the disc. The disc has two substantially flat data surfaces. The disc also includes a disc clamping portion located near the opening in the disc. A clamp is used to attach the disc to the hub. At least one disc is placed onto the hub and onto the mounting flange of the hub. The clamp is then used to clamp the disc to the hub. The disc clamping portion includes features for accommodating differences in flatness between the disc surfaces, the mounting flange of the hub and the clamp. The features include a first raised feature which extends above the first data surface of the disc, and a second raised feature which extends above the second data surface of the disc. The features are either bumps or annular rings positioned on the disc mounting surface. The bumps or rings may be formed using a laser. The ring may also include a multiplicity of individual bumps. As the disc is clamped to the hub, the raised feature deforms to accommodate the mismatch in flatness between the disc surfaces, the mounting flange of the hub, and the clamp. The clamp may include a roughened disc clamping surface. The upper surface of the disc mounting flange may also be roughened.

摘要： A disc storage system includes a rotating disc and a transducer. The transducer is carried on a slider which is supported by an armature. The armature is used to move the slider radially across the disc surface whereby information may be read from or written to the disc surface of the transducer. The slider includes an air bearing surface which faces the disc surface. As the disc rotates, the air bearing surface causes the slider to “fly” over the disc surface. Pads are provided on the air bearing surface to improve operational characteristics of the system.

摘要： An apparatus includes a slider body having a leading edge and an opposite trailing edge, as well as a top face and a bottom face each extending between the leading edge and the trailing edge. The slider body further includes a plurality of protrusions extending from the bottom face, a first recess defined on one of the protrusions, and a sacrificial layer deposited on the slider body in the recess. A bottom surface of the sacrificial layer extends at least as far from the bottom face as bottom surfaces of the plurality of protrusions. In another aspect, a first blocking feature is located at a first uptrack edge on an air bearing surface of a slider, with the first blocking feature being substantially continuous along the first uptrack edge and protruding outwardly from the air bearing surface to reduce particle interaction with the air bearing surface.

摘要： A method is disclosed for producing sliders with protective contacts features the fabrication of which is initiated at the wafer level. Recesses are formed in the wafer, a protective material is provided in the recesses, and the wafer is sliced along the recesses and diced into sliders, such that the protective material forms corners of the sliders. The protective material may be disposed such that it has a low elastic modulus at the corners, and a higher elastic modulus at a displacement from the corners which is still lower than the elastic modulus of the slider body, thereby providing superior protection for potential contacts between the slider and an adjacent media surface.

摘要： A data recording component includes a read transducer and a write transducer. A thermoelectric device generates heat flow between the read transducer and the write transducer. The heat flow is conducted by thermal conductors. A controlled current source provides current to the thermoelectric device that changes polarity to change directions of the heat flow and thereby vary a gamma ratio of transducer protrusion.
