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 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.
摘要:
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.
摘要:
Modifications to the indenter probe tips and transducer, and proper selection of optics in an indentation system allow straight down or slightly angled optical viewing of the sample surface under the indentation tip by a microscope, by providing an optical path through the transducer from the sample surface under the tip to a microscope objective, thereby simplifying alignment of the tip to features on the sample.
摘要:
A method and system for wirelessly transferring data and power via capacitive coupling. In some embodiments, a plurality of first electrodes is configured to wirelessly transfer power and data signals through an insulating layer to a plurality of second electrodes with capacitive coupling. In some embodiments, the insulating layer comprises at least a dielectric film.
摘要:
An electrostatic actuator for adjusting a spacing. A first body has an electrically conducting surface, and a second body has a body surface separated by the spacing from the electrically conducting surface. A conductor layer and an actuator electrode are recessed in the second body, and an electrode face faces the electrically conducting surface across the spacing. The actuator electrode comprises a semi-insulating material with a combination of electrical resistivity and thickness which prevents shorting of the conductor layer to the electrical conducting surface through a dielectric breakdown in the spacing.

A microactuator finely positions a transducing head carried by a slider adjacent a select radial track of disc. A frame of the microactuator includes a motor for altering the position of the slider and a closed bonding tub extending upward from the bottom of the microactuator having a bonding surface to engage the top surface of the slider. The closed bonding tub is formed from the microactuator frame such that there is a tub bottom having a bonding surface, sidewalls and an open sidewall.
摘要:
The slider and method of the present invention relate to a slider for a disc drive. The slider includes a substrate having a cavity and a filler within the cavity. The slider further includes a transducer that is positioned near the filler. The design facilitates controlling the relative thermal expansion between the transducer and substrate of the slider that is near the transducer. Compensating for the thermal expansion of the transducer provides a more consistent fly height of the slider during operation of the disc drive. In addition, the design adjusts the air-bearing surface of the slider such that the transducer does not extend below the rest of the slider as the transducer expands.
