Super-textured air bearing surface slider design for data transducers in rotating media random access computer mass storage devices

Abstract

A textured air bearing surface (“ABS”) slider design of particular utility in devices which utilize an air bearing surface to control the flying height or spacing between two relatively moving surfaces such as the sliders designed for use in conjunction with the read/write data transducer elements in a hard disk drive. The textured ABS slider provides much improved slider-to-media stiction and contact start stop (“CSS”) performance due to its provision of much earlier take-off characteristics which is of particular importance for use with high RPM drive designs which allow for higher data throughput. At low RPMs the fly height of the slider is increased while the fly height remains substantially the same at normal operating speeds. The textured ABS slider design disclosed may be readily effectuated with only minimal design and processing changes.
