Durable landing pads for a slider air-bearing surface (ABS) are formed of tetrahedral amorphous carbon (t-aC) by filtered cathodic arc deposition. A hard carbon overcoat of the ABS is pierced to anchor the pads. The t-aC is extremely hard and highly stressed, and the pads may be laminated with a stress-relieving material. A rotating angled etching such as ion milling may be performed to undercut the hard carbon overcoat and further anchor the pads. A rotating angled deposition of t-aC may also be performed to round the pad tops, which may be trimmed to smooth corners.

[ What is claimed is:] [1.]1. A head for reading or writing information on a relatively moving rigid disk, the head comprising:a body containing a transducer and having a leading edge separated from a trailing edge by a disk-facing surface, said disk-facing surface having an air-bearing portion and a recessed portion, with said air-bearing portion having a hard coating containing carbon and disposed over a substrate, anda plurality of microscopic pads attached to said body, projecting from said air-bearing portion and piercing said hard coating, each of said pads containing a pad material made of carbon atoms interconnected by sp.sup.3 bonds.
