摘要： The present invention is a glide height test slider for detecting asperities and irregularities on a surface of a rotating disc. A slider body has a plurality of edges defining its outer boundaries. The slider body has a piezoelectric element on at least one of its surfaces, and the piezoelectric element does not extend outside the outer boundaries of the slider body. First and second confronting conductors are patterned on the piezoelectric element so that an electric field generated by the piezoelectric element in response to a strained force due to vibration of the slider body induces a voltage between the first and second conductors representative of the vibration. The piezoelectric elements may be a separate element bonded to the slider body, or the slider body may be formed of a piezoelectric material to form the piezoelectric element.

摘要： A slider is provided for actively controlling a fly height of the slider relative to a data storage disc during operation of a data storage system. The slider includes a slider body having front and back surfaces, a length and a crown curvature on the front surface along the length. The slider also includes first and second elongated rails which are positioned on the front surface along the length of the slider body and form first and second bearing surfaces. Each bearing surface includes a leading portion, a trailing portion and a waist portion, wherein the waist portion is wider than the leading and trailing portions and has a maximum width within a middle half of the length of the slider body. A deformable material is positioned on the slider body having a dimension that is changeable in response to an electrical control signal applied in a deformable material, wherein a change in the dimension causes a change in the crown curvature.

摘要： An asperity height sensing head and method of using the same are disclosed. The head includes multiple magnetoresistive (MR) sensors carried by a first rail of a slider adjacent to the air bearing surface (ABS) and positioned a distance L.sub.p from each other. Asperity height estimating circuitry coupled to each of the multiple MR sensors detects a number N of the MR sensors which exhibit a change in resistance as a result of contact between the ABS and a first asperity on the surface of the disc. The asperity height estimating circuitry estimates the height H.sub.A of the first asperity as a function of the number N, as a function of the pitch angle .theta..sub.p , and as a function of the distance L.sub.p.

摘要： A magnetic data transducing slider is selectively textured, at least over its air bearing surface, to provide rounded nodules or rims adapted to support the normally aerodynamically supported slider when at rest on a specular surface of a data recording medium. The texturing substantially reduces the area of contiguous slider/medium contact as compared to the area of the air bearing surface, counteracting stiction and substantially reducing dynamic friction during head takeoffs and landings. Slider texturing eliminates the need for a dedicated contact or landing zone on the data recording medium, making more space available for storing data on the medium, and insuring a more uniform surface roughness over the entire surface of a medium that confronts the slider. The desired texture is formed according to a process that includes depositing chromium or another metal onto the slider substrate to provide metallic regions on the air bearing surface, particularly along opposite skis of the slider. Then, laser energy is concentrated upon the regions to form smooth, rounded support features, such as nodules or annular rims. The features can be uniform in size, or alternatively can exhibit a size gradient to support the slider at an incline that replicates its orientation when aerodynamically supported.
摘要翻译：至少在其空气支承表面上选择性地纹理化磁数据传感滑块，以便在数据记录介质的镜面上静止时适于支撑通常空气动力学支撑的滑块的圆形结节或边缘。与空气轴承表面的面积相比，纹理化大大减少了连续的滑块/介质接触的面积，抵消了静摩擦力，并且在头部起飞和着陆期间基本上减少了动摩擦力。滑块纹理消除了对数据记录介质上的专用接触或着陆区域的需要，使得更多的空间可用于在介质上存储数据，并且确保在与滑块相对的介质的整个表面上更均匀的表面粗糙度。根据包括将铬或另一种金属沉积到滑块基底上以在空气轴承表面上提供金属区域，特别是沿着滑块的相对滑雪板的方法形成所需的织构。然后，激光能量集中在这些区域上以形成平滑的，圆形的支撑特征，例如结节或环形边缘。特征可以在尺寸上是均匀的，或者可以表现出尺寸梯度，以在空气动力学支撑时复制其取向的斜面上支撑滑块。
