DATA RECORDING SLIDER HAVING AN AIR BEARING SURFACE PROVIDING HIGH PRESSURE RELIEF FOR VIBRATION DAMPING

摘要

A slider for magnetic data recording. The slider has an air bearing surface with a trailing edge pad that is configured with a series of recesses that damp slider oscillations during use. The series of recesses formed in the trailing pad of the slider reduce slider oscillations by creating localized pressure gradients within the generally high pressure area over the pad. The slider can be configured with a raised primary pad and a secondary raised pad formed on the primary raised pad. A series of recesses formed in the secondary pad prevent slider oscillations, which would otherwise be especially problematic in a slider having such a secondary raised pad and associated higher pressure area thereover.
