Patent number: 6583953Abstract: An overcoat overcoat for a head and/or media surface is made of a hard, dense and durable silicon-carbide (SiC) layer. The SiC layer does not require an interlayer to promote adhesion to underlying magnetic or ceramic layers, thus reducing head-media spacing and increasing areal storage density and resolution. The SiC is formed in a manner that creates an overcoat with density, hardness, durability and corrosion resistance similar to DLC. The SiC overcoat formation process also penetrates less into underlying magnetic layers than is conventional, reducing further the spacing of active elements by inactive coatings. In an alternative embodiment, SiC may be formed by this process as an interlayer for a carbon overcoat such as DLC or ta-C. This allows the overcoat to be made thinner, since the interlayer is hard and dense, while retaining the chemical and other surface properties of the carbon overcoat.Type: GrantFiled: July 12, 1999Date of Patent: June 24, 2003Inventors: Hua Han, Francis W. Ryan, Carolyn S. Robinson, Thomas P. Ultican

Patent number: 6236543Abstract: 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.Type: GrantFiled: January 29, 1999Date of Patent: May 22, 2001Assignee: Read-Rite CorporationInventors: Hua Han, Kelly D. Linden, Francis W. Ryan, Lee C. Boman
