摘要： The present invention provides a method of producing thin film elements which reduces the damage caused by handling the individual thin film elements. The method disclosed teaches formation of rows of completed thin film elements, such as air bearing sliders, defined by one of two methods namely: wafer processing or row processing to form partial cuts between device elements. The resulting partial cuts preserve the row structure after fabrication, e.g., for inspection and packing, but allow easy separation of the completed sliders just prior to assembly.

摘要： A tool, and associated method, for batch processing the definition of air bearing surfaces on rows (48) comprising a plurality of sliders is disclosed. The tool (60) comprises a main body member (76) having a recess (126) with a lateral wall (130) defining an x-axis alignment reference surface. A central platform (86) is positioned in the recess, having an upper surface (87) defining an upwardly facing z-axis base surface and a pair of pins (112) defining y-axis alignment reference surface. The rows (48) are positioned adjacent to one another on the upper surface (87) of the platform such that an anchor row engages the pins along its longitudinal side and abuts the lateral wall at its one end for aligning respectively with the y-axis and x-axis reference surfaces. All the rows have top surfaces lie in a common plane which is parallel with the z-axis base surface.

摘要： A method for determining the position of a lapped edge (23) of a substrate (11) during lapping of a row of thin film magnetic transducer elements (30). First and second electrical lapping guide structures (21, 22) are formed on each side of the row of transducer elements. The lapping guide structures include a series of switching junctions (32-35), each switching junction paralleled by a resistor (38-41). A lapping resistor (31) which provides a change in resistance proportional to the lapping of the row is measured and compared with the position of the lapping plane as determined from each switching junction change of state. Calibration of the resistor versus lapping plane position is effected to permit an accurate determination of the lapped surface from subsequent resistance measurements of the lapping resistor.

摘要： A wire bonding method wherein a gold alloy bond wire (244) with a diameter of less than about 25.4 μm is ball bonded to a gold alloy contact pad (218) without heating the underlying bonding pad (218) by using an ultrasonic bonding frequency greater than 60kHz and less than 200kHz. The ball bonding method allows the use of particularly small bonding pads that are particularly close to adjacent microelectronic structures that limit the use of other bonding techniques that have shallow take-off angles. Also describes an electronic storage device slider comprising a printed circuit board (234) and a bar (232) of microelectronic devices (226) wherein said method is used for obtaining the electrical connection between said parts.

摘要： In one aspect described herein, a read head having one or more magnetoresistive (MR) sensors (or devices) is provided. In one example, the read head includes an MR sensor (324) and an insulator layer (326) disposed at the same level as the MR sensor. The read head further includes a bearing surface, wherein the insulator layer (326) forms a portion of the bearing surface and is disposed between a surface of the MR sensor (324) and the bearing surface to provide protection for the MR sensor from exposure to the bearing surface. The MR sensor (324) may include a stack of thin-film layers to form an AMR, GMR, or TGMR sensor element. The stack may further include a slanted surface portion, wherein the insulator layer (326) is disposed on the slanted surface portion, thereby recessing the MR sensor (324) from the bearing surface.

摘要： Associated with decrease in flying height of a magnetic head slider, there arises a problem of destabilization of flying of a slider due to attachment of contamination to a flying surface of a magnetic head slider. Ions exerting an effect of decreasing surface energy are implanted in the whole surface of a flying surface of a magnetic head slider 1 except for a front rail surface 4 and a center rail surface 7. According to this, contamination is prevented from being attached to a front step bearing surface 5, a side step bearing surface 6, a center step bearing surface 8 and a negative pressure groove 9 where contamination is particularly liable to be attached in the flying surface of the magnetic head slider, so as to suppress destabilization in flying of the slider. The ion implantation in the whole surface of the flying surface of the magnetic head slider increases the surface roughness of the front rail surface 4 and the center rail surface 7, but in the case where ions are implanted by excepting the front rail surface 4 and the center rail surface 7 as in the invention, contamination may be effectively prevented from being attached to the flying surface without increase in surface roughness, whereby destabilization in flying of the slider may be suppressed.

摘要： According to one aspect, an exemplary method for manufacturing a magnetic head includes forming a plurality of magnetoresistive devices, a reference device, and a monitoring device, where the reference device includes a desired stripe height less than the magnetoresistive devices and monitoring device. Material is removed from the air/tape bearing surface, e.g., by lapping, thereby reducing the stripe height of the magnetoresistive devices and monitoring device. A characteristic of the reference device, e.g., resistance, voltage, or the like, is compared with a similar characteristic of the monitoring device, wherein the characteristic of the monitoring device varies as material is removed. Material may be removed from the bearing surface until the characteristic of the monitoring device and the reference device are substantially equal, at which time, the stripe height of the monitoring device and magnetoresistive devices are substantially equal to that of the reference device.

摘要： A method and apparatus for processing a magnetic transducer (10) uses a gallium ion beam (210) to precisely define a pole tip region of the magnetic transducer. The precision pole tip widths provide a transducer that may record correspondingly precise track widths on a magnetic storage medium, such as a rotating disk. During the ion milling process an image detector (207) determines an image of the pole tip region to control subsequent ion beam milling with either a focused or defocused ion beam. Subsequent to the ion milling process, the magnetically conductive properties of the pole tip region, which may be degraded as a result of unwanted ion implantation during the ion milling process, are restored by means of a lapping process.
