CSS magnetic recording head slider and method of making same

Year	Description
1995	Invention patented by Mark D. Moravec, Tu Chen, Tracy L. Scott, Kyou Haeng Lee, Tsutomu Tom Yamashita, and Tam Huu-Minh Nguyen on February 20th, 1995. Abstract: Definition of the required geometry of the air bearing surface ("ABS") of a magnetic head slider is achieved while providing an ABS which exhibits low wear, low friction, and low stiction at its interface with a disk surface, by securely embedding monocrystalline diamond particles into a lapping plate, removing substantially all particles from the plate which are not firmly affixed thereto, and lapping the slider in a linear, X-Y direction at a relatively high lapping pressure. Material susceptible to being dislodged during CSS is removed during the lapping process. Thus, the incidence of material dislodging from the ABS and increasing wear-induced stiction is substantially reduced, resulting in improved CSS performance. A desired microtexture is also applied to the ABS. Reduced pole tip recession is also observed.
