摘要： A disk drive is described having a capability of burnishing the sliders on demand by using a heater in the slider to thermally protrude the slider. Each slider includes a heating element with a sufficient thermal expansion stroke to bring the area of the slider containing the transducer into contact with the disk surface to burnish the slider. Preferably the heater is used to bring the slider into contact with the disk to burnish the lowest flying part of the slider body after the drive has been assembled, and remove most or all of the overcoat and recession, and exposing the transducers at the ABS. The burnish process is performed in situ in the drive and the drive is preferably hermetically sealed to reduce the risk of corrosion. The slider can be flown and magnetically tested prior to burnishing off the overcoat to avoid corroding the head before the drive is assembled.

摘要： An AAB slider has a leading edge generally impinging fluid flow due to movement of a medium relative to the slider. A cavity dam defines a continuous air bearing surface that extends over a region between the sides of the slider and between at least one sub-ambient cavity and the leading edge. Step level slots in the air bearing surface at the leading edge admit fluid into the region of the air bearing surface. Side rails on the slider extend rearward from the cavity dam to form the sub-ambient cavity. The air bearing surface is characterized by the absence of a channel adjacent the leading edge that extends between the sides of the slider. A center rail extends rearward from the cavity dam to the trailing edge and supports a transducer. The arrangement is such that airflow to the transducer is minimized, thus minimizing particulate matter from accumulating on the trailing edge slider features, including the transducer.
摘要翻译： AAB滑块具有通常由于介质相对于滑块的移动而引起流体流动的前缘。空腔坝限定连续的空气支承表面，其在滑块的侧面之间以及至少一个次环境空腔和前缘之间的区域上延伸。在前缘的空气轴承表面中的台阶槽允许流体进入空气轴承表面的区域。滑块上的侧轨从空腔坝向后延伸以形成次环境空腔。空气轴承表面的特征在于，在滑块的两侧之间不存在邻近前缘的通道。中心轨道从空腔坝向后延伸到后缘并支撑换能器。这种布置使得到达换能器的气流最小化，从而最小化包括换能器在内的后缘滑块特征上积聚的颗粒物质。

摘要： A method is disclosed for positioning an optical labeling mechanism substantially close to a particular track of a labeling surface on an optical disk. The method can include the operation of positioning the optical labeling mechanism adjacent to the particular track. A further operation can be measuring a first surface texture of the labeling surface using the optical labeling mechanism. Another operation can involve positioning the optical labeling mechanism adjacent to a different track. A further operation can be moving the optical labeling mechanism from the different track toward the particular track location. Another operation can involve measuring a second surface texture of the labeling surface using the optical labeling mechanism. A further operation can be comparing the first and second surface textures to determine if the optical labeling mechanism is positioned substantially near the particular track.

摘要： A magnetic head (slider) which requires no lapping is described. The head is fabricated with an air bearing surface that is parallel to the wafer surface. The saw cuts used to separate the individual sliders from the rest of the wafer are perpendicular to the air-bearing surface and do not pass through any critical features. The read and write components are formed from thin films disposed parallel to the air bearing surface and can be side-by-side or tandem in relation to the recording track. The stripe height of the read sensor is controlled by the deposition process rather than by lapping. Various embodiments of the read head include contiguous junction biasing, external hard magnet biasing, and in-stack biasing. In one embodiment a permeable field collector is included below the sensor layer structure. An aperture shield surrounding the sensor at the ABS is included in one embodiment.

摘要： A slider-mounted transducer has an integral wear pad for determining interference between the transducer and a disk surface. The wear pad intensifies interference events during disk drive testing and enables the threshold for slider fly-height to be set at a lower level. This, in turn, improves disk drive reliability during normal operation. The wear pad can be a carbon overlay deposited near the trailing edge of the slider or it can be an un-etched strip of alumina within a recessed region of the slider. The wear pad is substantially worn away during the test period, so it does not affect subsequent operation of the drive.
摘要翻译：滑块安装的换能器具有用于确定换能器和盘表面之间的干涉的整体磨损垫。磨损垫在磁盘驱动器测试期间加强了干扰事件，并使滑块飞行高度的阈值设置在较低的水平。这反过来又提高了正常运行时的磁盘驱动器的可靠性。耐磨垫可以是沉积在滑块的后缘附近的碳覆盖层，或者它可以是在滑块的凹陷区域内的未蚀刻的氧化铝条。在测试期间磨损垫基本磨损，因此不影响驱动器的后续操作。

摘要： With a view to providing a head slider which can suppress the adhesion of dust particles to a flying surface of the head slider when the head slider flies and a disk drive employing the same head slider, a head slider in which at least an air bearing portion and a land portion for forming a vacuum area on the flying surface are provided on the flying surface of the head slider, the land portion being formed in such a manner as to have a difference in level so as to be closer by a step to a disk medium than an end surface of the slider base, wherein the water repellency of an end surface of the land portion and the water repellency of the end surface of the slider base are made higher than the water repellency of the air bearing portion. As this occurs, the water repellency of the end surface of the land portion is increased more than the water repellency of the air bearing portion, whereby the water repellency of the end surface of the slider base can be increased more than the water repellency of the end surface of the land portion.

摘要： A pair of side pads, which are arranged to face each other by having a negative pressure generating part in the direction orthogonal to an air flow direction of a slider therebetween, are made to have three or more steps, respectively. Of the respective surfaces having the plural steps, the surfaces having a highest height respectively are not subject to a milling, and the respective surfaces of having plural steps are made to gradually have a deeper cavity depth as the surface comes closer to the air inflow end. Further, it is also effective for improving the efficiency in positive pressure generation to surround the second side pad region partially by the region of the surface being not subject to the milling, and to surround the third side pad region partially by the second surface region.

摘要： A head stack assembly is provided for interfacing with a flexible medium of a disk. The head stack assembly includes a first head and a second head located substantially adjacent to the first head wherein the flexible medium may be disposed between the first head and the second head. The first head and the second head are substantially parallel to each other and disposed at a static roll angle θa and a static roll angle θb, respectively, from the flexible medium to impart a curvature to the flexible medium of a disk. The curvature reduces out-of-plane vibrations of the flexible medium and thereby enhances the electrical communicative signal between the flexible medium and the first and the second heads.

摘要： A method for forming an electrical interconnect to the spring metal layer in an integrated lead suspension or suspension component of the type having a multi-layer structure including a spring metal layer and a conductor layer separated by a dielectric insulator layer. The method includes forming an aperture through at least one of either the spring metal and conductor layers, and optionally through the dielectric layer, at an interconnect site. A first mass of malleable conductive metal is inserted into the aperture. The mass of metal is then coined to form a stud that engages at least the spring metal layer at the interconnect site. One embodiment of the invention is used to form a bond pad stud that is free from contact with the conductor layer. Another embodiment is used to form an electrical interconnect stud that electrically connects the spring metal and conductor layers. The invention can also be used to mount integrated lead flexures to load beams.
