A head for use in a magnetic hard disk drive or other information storage
device includes a novel air bearing surface. The novel air bearing
surface includes two leading pads separated by a longitudinal channel,
and a trailing pad. The leading pads and trailing pad each include a
major surface that lies in a first plane. A side pad, laterally spaced
from the trailing pad, includes a major surface that lies in a second
plane that is parallel to the first plane but that is offset from the
first plane by a shallow recess depth in the range of 0.5 microinches to
two microinches. The side pad also includes a major surface that lies in
a third plane that is parallel to the second plane but that is offset
from the first plane by standard recess depth in the range of three to
five microinches.
