Disk drive with negative-pitch slider having protrusion pad contacting the disk when the disk is rotating at operating speed

A magnetic recording disk drive has a negative-pitch slider in near-contact or continuous-contact with the disk during reading and writing of data. When the disk is rotating at its operating speed, the slider has its upstream or leading portion located closer to the disk surface than its downstream or trailing portion. Both the leading and trailing portions have air-bearing surfaces that enable the slider to be partially supported above the disk surface. A contact pad that provides no substantial air-bearing support is located at the leading portion and supports or contains the magnetic elements of the read/write head. The contact pad protrudes beyond the air-bearing surface of the leading portion and is in contact with the disk. For near-contact recording the contact pad partially wears away during an initial wear-in period. For continuous-contact recording the contact pad is wear-resistant and remains in substantially continuous contact with the disk during reading and writing of data.
