Zusammenfassung:In modern high speed disc drives, the recording head slider is usually maintained at a very small distance above the recording media. Typically, this distance is 25 nm. The disc is lubricated to improve its durability. Modern discs usually use a long chain polymer lubricant. A method and system is presented for a slider positioned to control a flow of lubricant over the slider body. The slider can also include a raised rail. A pad can be positioned on the slider between the raised rail and a trailing edge of the slider. The pad can extend to the trailing edge of the slider. The pad can include at least two separated edges, which form a central channel. The pad can be made of carbon. The pads can be approximately 0.03 micron tall in a cavity that is approximately 2 micro deep. The pad can be angled in relation to an air flow across the slider to control lube.
