摘要： A magnetic data storage medium includes a dedicated transducing head contact zone for engaging an air bearing slider, primarily when the disk is stationary. The contact zone is textured with at least one elongate ridge extending in the circumferential direction. When a single ridge is formed, it runs in a spiral path in multiple turns with a predetermined radial pitch at least ten times the nominal ridge width. The ridge protrudes axially outward from a nominal surface plane of the contact zone, and is rounded and free of sharp edges. The ridge, or plurality of ridge sections, can be formed by a texturing process that includes directing a laser beam, focused, onto the contact zone surface. While the disk is rotated to maintain a constant circumferential speed relative to the laser, it also is translated radially to provide the desired radial pitch. The laser is operated in a CW (continuous wave) mode, to create a more uniform ridge.

摘要： The present invention is used to form precise, optically detectable patterns on rotating members of a disk and spindle assembly of a disk drive used in data storage system. In particular, the invention employs an optical source to form optically detectable patterns on the rotating members of the disk drive. These optically detectable patterns are used to create an accurate clock track. The clock track may be used to create multiple accurate magnetic patterns on one or more disks attached to a disk and spindle assembly in a magnetic data storage system. By successively changing the radius at which the magnetic patterns are created it is then possible to create multiple magnetic patterns at successive radii with all such magnetic patterns having a precise geometric relationship to each other. Alternatively, the accurate clock pattern may stand alone as an encoder. Additionally, the present invention may also be used to form textured surfaces on a disk to control the flying characteristics of a magnetic head slider assembly. The present invention can also create textured surfaces which will serve as a resting area for the magnetic head slider assembly of a magnetic disk drive when the disk is not spinning.

摘要： A magnetic data storage medium includes a dedicated transducing head contact zone for engaging an air bearing slider, primarily when the disk is stationary and also during disk accelerations and decelerations. The contact zone has a dual baseline texture, formed by first creating a recessed region within the transducing head contact zone, and then by forming multiple nodules or other texturing features within the recessed region. The texturing features project upwardly from a recessed surface of the recessed region, and also project above an upper surface of the disk by an amount less than the texturing feature height. Consequently, the texturing features are large enough to counteract stiction due to liquid lubricant meniscus formation, yet also have heights sufficiently low relative to the upper surface to allow reduced transducer flying heights. According to a preferred texturing process, the recessed region consists of multiple individual recesses produced by applying a carbon layer to the disk, then forming cavities by selective laser ablation of the carbon layer.
摘要翻译：磁数据存储介质包括用于接合空气轴承滑块的专用换能头接触区，主要是当盘静止时以及在盘的加速和减速期间。接触区域具有双基线纹理，首先在传感头接触区域内形成凹陷区域，然后通过在凹陷区域内形成多个结节或其它纹理特征而形成。纹理特征从凹陷区域的凹陷表面向上突出，并且还以小于纹理特征高度的量突出在盘的上表面上方。因此，纹理特征足够大以抵消由于液体润滑剂弯液面形成导致的静摩擦，而且还具有相对于上表面足够低的高度，以允许减小的换能器飞行高度。根据优选的纹理化工艺，凹陷区域由通过将碳层施加到盘而产生的多个单独凹槽，然后通过碳层的选择性激光烧蚀形成空腔。
