My thanks to Dave Kleiman (one of the original papers [8]co-author's with myself) for reviewing and adding to this series of postings.

Drive technology is set to change in the near future with patterned media (which uses a single pre-patterned large grain per bit)1. It is this type of technology, which will soon allow us to achieve "Terrabit per Square Inch" recording densities. fig12Figure 1 - A Single Track with a Patterned Media Drive

Conventional magnetic media has been made from the grouping of sub-10nm magnetic grains. These grains have traditionally been able to form an individual magnetization
