Hard Disk Read/Write Head Technologies

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.
