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.
