20090009906 | Transducer Assembly and Data Storage Device Including the Transducer Assembly - An apparatus includes a storage medium, a transducer positioned adjacent to the storage medium and along an axis, and first and second support members connected to the transducer at positions that are spaced apart in the direction of the axis. | 01-08-2009 |
20090052084 | SLIDER WITH CONTACT FEATURES INITIATED AT WAFER LEVEL - 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. | 02-26-2009 |
20090282933 | FOLDED BEAM SUSPENSION FOR PROBE - Probe structures that utilize a folded beam structure to support the probe tip. The folded beam or supported-beam structure provides a linear spring force over a large displacement range while resisting probe tip tilting and lateral motion of the probe tip. In one embodiment, the probe structure has a supported-beam structure comprising an inner beam structure surrounded by an outer support, the inner beam structure pivotally connected to the outer support. The inner beam structure has a central region and the outer support having outer corner regions. The outer corner regions provide an attachment region to a supporting mechanism for the probe structure. A probe tip is located at the central region of the inner beam structure. The probe structure may have at least three arms, for example, four arms. | 11-19-2009 |
20090302869 | PROBE WITH ELECTROSTATIC ACTUATION AND CAPACITIVE SENSOR - A supported probe device that has a probe tip and probe body, the probe body having a sample facing surface and an opposing surface. The probe tip and a first electrode are on the sample facing surface. A second electrode is present on the probe body opposing surface. A third electrode is spaced from the second electrode, so that the second electrode is between the third electrode and the probe body. A first DC voltage source is electrically coupled to the first electrode, as is a first sensing circuit. A second DC voltage source is electrically coupled to the second electrode, and an AC voltage source electrically coupled to the third electrode. The probe body may be cantilevered. | 12-10-2009 |
20090315548 | HIGH SENSITIVITY MAGNETIC SENSOR - A sensor device comprising a base substrate and first and second flux concentrator fixedly attached to the base substrate. The first flux concentrator and the second flux concentrator are positioned with their proximal end regions facing and spaced apart, defining a gap therebetween. A magnetic sensor element is positioned in the gap, the sensor element moveable towards and away from the base substrate. The sensor device has a first system to offset stray magnetic fields, a second system to modulate the sensor element to detect KHz frequency, and a third system to dither noise from the first and second flux concentrators. | 12-24-2009 |
