    摘要： An apparatus for measuring a curvature of an air bearing surface (ABS) of a read/write magnetic head slider. The apparatus has two lasers which direct laser beams toward the ABS. The beams strike the ABS and are specularly reflected. The reflected beams are directed toward a position sensing optical detector. The distance between the points where the beams strike the detector is indicative of the curvature of the ABS. The beams my be alternately pulsed so that the detector outputs a DC-biased square wave signal, the voltage-step difference of which indicates the curvature. In another embodiment, a single laser beam is scanned by a scanner and passed through a scan lens. The scan lens is located one focal length from the scanner. A reflected laser beam is reflected from the ABS and is collected by the scan lens. The reflected laser beam is then directed toward a position sensing optical detector. The detector is located outside the focal plane of the scan lens. The position of the laser beam on the detector is dependent upon the curvature of the ABS. Then the magnitude of the detector output provides a measure of the curvature.

    摘要： A method for adjusting the curvature of an air bearing surface (ABS) of a slider having a back surface opposite the ABS. The method includes steps of repeatedly measuring the curvature of the ABS and scribing lines (e.g. with a laser scribing tool) on the back surface to partially adjust the curvature of the ABS. In each measuring/scribing installment, the curvature of the ABS is measured and compared with a final target curvature to determine a curvature difference between the measured curvature and final target curvature. Each installment of scribing lines corrects for a predetermined percentage of the curvature difference. The predetermined percentage may be different in succeeding installments. Alternatively, each installment changes the curvature of the slider to match an intermediate target curvature. In a three-installment process, for example, there will be two intermediate target curvatures and a final target curvature.

    摘要： A slider of a magnetic hard disk drive has one or more electric lapping guides in immediate proximity to the read/write stack of the slider. The lapping guides remain part of the slider during its operation. In the preferred embodiment, two essentially identical lapping guides are symmetrically placed on a slider back. One write head terminal is utilized to conductively access the two lapping guides on one side such that only one additional terminal has to be placed on the slider back together with corresponding leads. The placement of lapping guides on the slider back face provides for an economic lapping of individual sliders with increased precision and reliability regardless of any lapping plane skew.

    摘要： The present invention generally relates to fabricating a bond pad for electrically connecting a laser diode to a slider and a TAR head in a HDD. The bond pad is deposited on a surface of the head that is perpendicular to the air bearing surface (ABS). The head is diced and lapped to expose the bond pad on a top surface of the head and mounted on a slider. The laser diode and a sub-mount may be coupled to the top surface of the slider—i.e., the surface opposite the ABS—by connecting to the bond pads. Specifically, both the laser diode and the sub-mount have electrodes thereon that are perpendicular to the bond pads. Conductive bonding material is used to bond the laser diode and the sub-mount to the bond pads.
