Magnetic head air bearing slider

摘要

An air bearing slider of a thin film magnetic head assembly is configured with tapered portions at its leading edge and with two side rails extending from the tapers to the trailing edge of the slider. Recesses that are formed in the rails are spaced from the tapered portions. Each rail may be configured with one or more recesses. In one embodiment, the two recesses of each rail are asymmetrically disposed relative to the tapered portion of the rail and to the trailing edge of the slider. In such embodiment, the recesses do not extend to the slider trailing edge. In alternative embodiments, the recesses are spaced from the tapered portions but extend to the trailing edge of the slider. The recesses may be arcuately shaped or have angled portions or other geometries.
