Abstract
A novel air bearing can be used in a magnetic hard disk drive or other information storage device. The novel air bearing includes a central cavity having a bottom surface, a leading pad adjacent to the central cavity, a trailing center pad having a top surface, and two inter-projection step regions. The trailing center pad has an aft region adjacent to the transducer and three projections extending from the aft region towards the central cavity. The central cavity separates the three projections from the leading pad. Each of the two inter-projection step regions lies at least partially between the projections, and each includes a surface at an intermediate level between a level of the top surface and the level of the bottom surface. The novel air bearing may be adequately insensitive to one or more factors affecting flying height variation in a micro-drive utilizing ramp load/unload of the slider.
