The head of a disk drive has write elements disposed on one protrusion pad that
wears away during initial operation to permit reduced tolerances and, thus, reduced
spacing between the disk and head, with the read element being disposed on a separate
protrusion pad and spaced from the write element pad in the radial dimension. This
prevents read element recession during cooling in the absence of write current
that could otherwise occur if the read element were located on the same pad as
the write head.
