摘要： A method for making a magnetic head slider (10) comprising the steps of lapping the slider to form an air bearing surface (12), producing a chosen pattern of rails (14, 16) on the air bearing surface, and producing a chosen pattern of stress on the back side of the slider to remove the distortion produced in the slider by the lapping and rail formation steps. The stress pattern can be chosen to produce any desired range of crown and camber for the slider.

摘要： Apparatus for producing a line source of a desired shape from a light source (10) such as an excimer laser comprising means (12,14,16) for directing the light source along a predetermined path to a cylindrical lens (18) positioned to produce a vitural line image S' having uniform intensity along its length at a first location. However, the image is intercepted by a cylindrical mirror(20) inclined at an angle so that the beam is transformed into a curved shape and directed onto a quartz diffuser (22). This apparatus produces a curved self-luminous distribution having uniform intensity over its length. In a specific embodiment, the diffuser is a directional diffuser.

摘要： A data recording disk drive a low-flying air-bearing slider that is also able to be in contact and near contact with the lubricant film on the disk. The slider has a front air-bearing surface in the form of a pair of equally-spaced air-bearing pads 25, 27, a rear air-bearing pad 29, and a central nonair-bearing recessed surface 28 which separates the front and rear air-bearing pads. The two front pads have a surface area greater than that of the rear pad and thus provide a positive pitch up of the slider. This causes the rear pad to also be pitched up so that air can flow beneath the rear pad to generate an air bearing in the rear portion of the slider. The presence of the central nonair-bearing region eliminates any lift in the central part of the slider, which allows for the low-flying height. The flying height of the rear pad of the slider above the disk is controlled by the width of the rear air-bearing pad. The rear pad has its leading edge 31 wider than its trailing edge 33 so that it is able to withstand contact with the lubricant film on the disk, typically at the lower disk velocities near the disk inside diameter, without generating unacceptable drag forces or depleting the lubricant from the disk. The rear pad also has a skewed leading edge which compensates for skew of the slider to minimize the flying height variation from the disk inside diameter to outside diameter.
摘要翻译：数据记录盘驱动也能够与盘上的润滑剂膜接触并接近的低飞行空气轴承滑块。滑块具有一对等间隔的空气轴承瓦片25,27，后空气轴承瓦片29和中央非承载凹面28的形式的前空气轴承表面，其分隔前后空气垫两个前垫的表面积大于后垫的表面积，从而提供滑块的正间距向上。这使得后垫也被倾斜，使得空气可以在后垫下方流动，以在滑块的后部中产生空气轴承。中央非承载区域的存在消除了滑块中部的任何升力，这允许低飞行高度。盘上方滑块后排垫片的飞行高度由后空气垫片的宽度控制。后垫片的前缘31比其后缘33宽，使得其能够经受与盘上的润滑剂膜的接触，通常在盘内径附近的盘下速度较低，而不产生不可接受的阻力或耗尽润滑剂从磁盘。后垫还具有倾斜的前缘，其补偿滑块的偏斜以最小化从盘内径到外径的飞行高度变化。

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.
