unconventional magnetic recording

by with No Comment computingPhysics

Given the previous posts on magnetic recording, we are now in the position to look at unconventional magnetic recording. In other words, instead of applying a write field of sufficient strength to switch magnetic grains, we look at other ways to switch a magnetic grain. This has become to be known as “energy assist magnetic recording”. In future recording systems this will be required since there is a limit on the applied field one can produce in a small area....
