    摘要: A disc head slider supports a transducer relative to a data storage disc. The slider includes a slider body having a disc-facing surface with a leading slider edge, a trailing slider edge, and first and second slider corners at opposing ends of the trailing slider edge. First and second rails are disposed on the disc facing surface about a central recess and form first and second bearing surfaces, respectively. The central recess has a depth measured from the first and second bearing surfaces. First and second recessed surfaces are positioned between a trailing edge of the first and second rails and the first and second slider corners, respectively, and are generally coplanar with the central recess. Third and fourth recessed corner surfaces are positioned at the first and second slider corners, respectively, and are recessed from the first and second recessed surfaces.

    摘要: A method of contouring a surface of a slider for supporting a transducer relative to a data storage medium includes applying a lithographic resist layer to the slider surface. The resist layer is then exposed through a single mask having 3a mask pattern defined by variation in an optical density through the mask. The resist layer is exposed in an exposure pattern corresponding to the mask pattern. Portions of the resist layer are removed as a function of the exposure pattern to produce a vertically contoured resist layer. The slider surface is etched through the vertically contoured resist layer during a single etching step to form a vertically contoured surface feature within the slider surface.

    摘要: A self-loading disc head-slider has a slider body, with a leading slider edge and a trailing slider edge, and first and second raised rails. Each raised rail has a leading rail edge, inside and outside rail edges and a bearing surface. A cavity dam extends between the first and second raised rails. A subambient pressure cavity trails the cavity dam, between the first and second raised rails. A stepped leading taper extends from the leading slider edge to the bearing surfaces of the first and second raised rails. The stepped leading taper is formed of first and second steps. The first step is positioned along the leading slider edge. The second step wraps around the leading rail edges of the first and second raised rails and extends along a portion of the inside and outside rail edges of the first and second raised rails. The first and second steps have a step height of 0.05 to 1.5 microns.

    摘要: An air bearing slider for a disc drive includes an air bearing surface defined on the disc opposing face at least in part by a first step or cavity. An additional corner step is defined in bar processing, deeper than the first cavity. With the corner step, the first cavity does not extend quite all the way to the corner of the slider. The corner of the slider, formed on one face by dicing of the bar into individual sliders, is at an additional depth due to the corner step. The corner steps are preferably narrow, such as nominally one to two times the tolerance value on the dice cut. If a shock event occurs which causes the air bearing slider to contact the disc at certain roll and pitch angles, the corner step edge will contact the disc rather than the dice cut corner. The corner step thus lessens the probability of contact between the disc and the corners of the air bearing slider, and contact with a dice cut edge of the slider is avoided. This reduces the amount of damage to the disc drive caused by the shock event.

    摘要翻译: 用于盘式驱动器的空气轴承滑块包括至少部分地由第一台阶或空腔限定在盘相对面上的空气轴承表面。 在条形处理中定义了一个额外的拐角步骤,比第一个空腔更深。 在拐角步骤中,第一个腔不能完全延伸到滑块的拐角处。 由于拐角步骤,通过将棒切割成各个滑块而在一个面上形成的滑块的角部处于另外的深度。 拐角步骤优选地是狭窄的,例如标称是骰子切割的公差值的一到两倍。 如果发生冲击事件,导致空气轴承滑块以某种滚动角度和俯仰角接触圆盘,则角落边缘将接触圆盘而不是切屑角。 拐角步骤因此减小了盘与空气轴承滑块的角部之间的接触的可能性,并且避免了与滑块的切屑边缘的接触。 这样可以减少因震动事件造成的磁盘驱动器的损坏。

    摘要: A load/unload device to remove the slider from the proximity of the magnetic recording surface of a disk in a disk drive whenever the disk is to be stopped. The load/unload device is a ramp-like wedge which extends generally radially from the center of the magnetic disk and to the magnetic recording surface of the magnetic disk. When the slider is moved toward the center of the disk by an actuator mechanism, the end of the load arm supporting the slider, referred to as a tang, will engage the inclined plane of the wedge and lift the slider from the surface of the magnetic disk as the slider is translated closer to the center of the disk. Once the slider has been removed from close proximity of the disk, the tang may engage a trough-like surface on the structure supporting the wedge and will effectively detent the position of the slider through the forces exerted on the tang by the load beam of the actuator. Thus the disk will be protected from undesirable and damaging impacts of the slider against the magnetic recording surface of the disk thereby prolonging disk utility.

    摘要: A disc drive having an actuator arm to support a slider carrying a transducing head adjacent a selected data track of a disc having a plurality of concentric data tracks includes a microactuator on a leading edge surface of the slider to effect fine positioning of the transducing head with respect to the selected track. The microactuator includes a spatial region on the leading edge surface of the slider. A microactuator element spans the spatial region and is responsive to a voltage to selectively expand and contract, thereby bending to alter the position of the slider and the transducing head.

    摘要: An apparatus, and method of forming the same, for measuring a head-to-disc contact force in a magnetic disc storage system are disclosed. A slider body of the head has a trailing edge and an air bearing surface. A flexible beam is formed on the slider body at a corner between the air bearing surface and the trailing edge. Contact between the flexible beam and the disc causes deflection of the flexible beam. A degree of deflection of the flexible beam is indicative of the force caused by contact between the head and the disc. The apparatus includes first and second electrical access terminals for use in determining a parameter indicative of the quantity of deflection of the flexible beam and thereby of the force caused by contact between the head and the disc.
