The wear life of the head and disk is a function of the drag and normal load, as well as the material properties of the two rubbing surfaces. One indicator of wear is the frictional force developed between the two surfaces. At zero frictional force there would be no wear, and as the frictional force increases, the wear increases proportionally.
