Description
Summary:This paper introduces a new technique for reading and writing data in a MAMMOS system in which the position rather than the presence of domains is detected. We will refer to this new technique as domain position detection or DPD-MAMMOS. DPD-MAMMOS has several advantages over conventional MAMMOS and mitigates a number of common problems. Through computer simulation, it is shown how this technique can increase power margins and increase storage density. At the same time, DPD-MAMMOS eliminates the need for clock recovery, and relaxes the requirements on coil design.
