Abstract:
1. A magnetic recording disk drive comprising: a rotatable magnetic recording disk; a slider for supporting a magnetic recording head and comprising (a) a leading portion exposed to gas flow induced by the rotating disk and having a gas-bearing surface, (b) a trailing portion downstream from the leading portion and having a gas-bearing surface substantially coplanar with the gas-bearing surface of said leading portion, and (c) a protrusion pad on the leading portion, wherein the leading-portion of the slider is closer to the disk than the trailing portion of the slider, the protrusion pad is closer to the disk than the gas-bearing surface of said leading portion and is in contact with the disk when the disk is rotating at operating speed; a head on the slider leading portion for reading and writing data on the disk; and an actuator connected to the slider for moving the slider and head across the disk when the disk is rotating.
