There are several different technology families that have been employed to make hard
disk read/write heads. Usually, to enable hard disk speed and capacity to progress to
higher levels, adjustments must be made to the way the critical read/write head operation
works. In some cases this amounts to minor tweaking of existing technologies, but major
leaps forward usually require a breakthrough of some sort, once the existing technologies
have been pushed to their limits.
