摘要： A method and apparatus is described for gradually transitioning a slider from operation over a patterned data zone to landing on a patterned CSS zone. The ratio of raised area width to recessed area width of a pattern in a transition zone and/or CSS zone may be varied across the radial dimension of the disk. By changing the ratio of raised area width to recessed area width of the pattern in the transition from slider operation over the data zone to landing in the CSS zone, it is possible to gradually change the height of the slider from flying to non-flying conditions.

摘要翻译：描述了一种方法和装置，用于逐渐地将滑块从图案化数据区域上的操作转移到图案化的CSS区域上的着陆。过渡区域和/或CSS区域中的图案的凸起区域宽度与凹陷区域宽度的比可以在盘的径向尺寸上变化。通过改变从滑块在数据区操作到CSS区域的过渡中图案的凸起区域宽度与凹进区域宽度的比率，可以逐渐地将滑块的高度从飞行状态改变为非飞行状态。

摘要： A method for manufacturing a magnetic disk comprises the acts of a) applying a laser beam to at least a portion of a silica-containing substrate, thereby forming a set of bumps or ridges; b) etching the substrate to remove the ridges and form a set of valleys where the ridges were previously formed; and c) depositing an underlayer, a magnetic layer, and a protective overcoat on the substrate. A lubricant layer is then formed on the disk. The valleys formed in the substrate reduce stiction exhibited by the magnetic disk. However, the valleys do not interfere with the fly height of a read-write head used in conjunction with the magnetic disk.
摘要翻译：制造磁盘的方法包括以下动作：a）将激光束施加到含二氧化硅的衬底的至少一部分，从而形成一组凸起或凸起; b）蚀刻基板以去除脊，并形成一组预先形成脊的谷; 以及c）在基底上沉积底层，磁性层和保护性外涂层。然后在盘上形成润滑剂层。在基板上形成的谷减少由磁盘表现出的粘性。然而，谷不会干扰与磁盘一起使用的读写头的飞行高度。

摘要： A method for manufacturing a substrate for a magnetic disk comprises the acts of mounting a workpiece on a spindle; rotating the workpiece and scribing the workpiece to form first and second scribe lines on the top surface of the workpiece and first and second scribe lines on the bottom surface of the workpiece; and breaking the workpiece along the first and second scribe lines. The first scribe line on the top and bottom surface of the work piece defines the outer diameter of the substrate. The second scribe line on the top and bottom surface of the workpiece define the inner diameter of the substrate. Because scribe lines are formed on the top and bottom surfaces of the workpiece, the edge of the substrate is less jagged than substrates that are merely scribed on one side of the workpiece and then broken. Because the scribe lines are formed by mounting the workpiece on a spindle and rotating the substrate, the scribing can be done more precisely and quickly than scribe lines formed using an x-y platform.
摘要翻译：一种用于制造用于磁盘的基板的方法包括将工件安装在主轴上的动作; 旋转工件并对工件进行划线以在工件的顶表面上形成第一和第二划线，并在工件的底表面上形成第一和第二划痕线; 并沿着第一和第二划线断开工件。工件的顶部和底部表面上的第一划线限定了基底的外径。在工件的顶部和底部表面上的第二划线限定了衬底的内径。由于划痕线形成在工件的顶表面和底表面上，因此衬底的边缘比仅仅刻划在工件的一侧上然后断裂的衬底较少锯齿。由于划线是通过将工件安装在主轴上并旋转基板而形成的，所以与使用x-y平台形成的划痕线相比，划线可以更准确和快速地进行。
