摘要： A system and method for measuring and neutralizing the electrical charge at the interface of a magnetic head and a magnetic storage medium, such as a disk, is disclosed. A surface treatment material is applied to the magnetic head. The surface treatment material matches the medium surface material on the surface of the magnetic storage medium. The surface treatment material on the magnetic read/write head may be a fluorinated carbon, such as a Fomblin Z-derivative, perfluoro alkyl trichlorosilane, a FC-722, or a fluorinated polymer. The surface treatment material can be applied to the magnetic head by a vapor deposition process or by a liquid immersion process. The charge on the head-disk interface can be measured by applying varying external charges to the head while reading a signal previously written to the disk.

摘要： An air bearing slider including a recessed cavity surface to provide an adaptable bearing surface to compensate for thermal expansion or pole tip protrusion. The recessed cavity surface forms a leading edge cavity step to a raised bearing surface proximate to a trailing edge of the slider. The leading edge cavity step forms a rampless air bearing surface proximate to the trailing edge of the slider which is adaptable to form a ramp to pressurize a protruding surface of a transducer portion of the head.

摘要： One embodiment of the present invention pertains to a slider that includes a substrate, a transducer tip disposed on the substrate, and a hydrodynamic surface including a responsive aeroelastic deposit. The substrate has a first coefficient of expansion responsive to a stimulus. The transducer tip has having a second coefficient of expansion responsive to the stimulus that is greater than the first coefficient of expansion. The aeroelastic deposit has a third coefficient of expansion responsive to the stimulus that is greater than the first coefficient of expansion. The responsive aeroelastic deposit allows the slider to alter its flight characteristics responsively and elastically to changing operating conditions.

摘要： The present invention provides a device for in-situ measurement and recording of various environmental parameters in a semiconductor fabrication process. The device comprises sensors for detecting the parameters and converting them to sensor outputs; and a data logger coupled to the sensors for receiving the sensor outputs and logging them in a file. The device may also comprise an analog to digital converter to convert the sensor outputs to digital data and a communication module to communicate the digital data with other devices. When applied to reticles used in a semiconductor fabrication process comprising a plurality of stages, the device may be used to monitor electrostatic field and electrostatic discharge activities on and around the reticle, convert the monitored parameters into data, and log the data along with a timestamp and an identification of each individual stage. Logged data can be retrieved and analyzed to determine the time and location of detrimental activities such as electrostatic discharge on reticles.

摘要： A head includes a bearing surface portion disposed between two transition surface portions which progressively diverge away from a plane containing the bearing surface portion. The bearing surface portion and transition surface portions collectively form a generally continuous surface which is substantially free of abrupt discontinuities in a head travel direction. A method of making the head involves use of a gray-scale mask to pattern a photoresist on a substrate, after which the photoresist is developed and the substrate is etched through the photoresist in order to create on the substrate a three-dimensional surface which includes the bearing surface portion and transition surface portions.

摘要： A magnetic head slider in which a leading pad is projected in a thicknesswise direction of the slider, in comparison with a trailing pad so as to reduce vibration caused by contact between a flat medium surface of a disc and the slider carrying thereon a magnetic head, to reduce variation in flying height caused by wavy unevenness of the medium surface, and to reduce variation in atmospheric pressure around the slider, thereby it is possible to enhance the recording density and the reliability of the magnetic head slider while reducing the costs thereof. Further, a magnetic disc unit using the above-mentioned magnetic head slider.

摘要： The present invention is directed towards air-bearing sliders that are used in disk drives. The invention involves pitching a slider so that the leading portion of the slider is closer to the disk than the trailing portion of the slider. The negative pitch reduces the sensitivity of the slider to ambient air pressure, radial position, and to data accessing over the disk. When used in combination with a reverse-flow disk drive, negatively pitched sliders facilitate the routing of traces to the head.
