Exchange Coupled Composite Media for Magnetic Recording – Issues and Challenges

Article Preview

Abstract:

The paper is devoted to the analysis of the exchange coupled composite (ECC) media. The principle of ECC media, the switching process and the thermal stability of these media are analysed. The features of ECC media ask for some changes in the design of recording heads; a lot of proposed geometries of these heads are presented. Finally, challenges and possible improvements of ECC media are summarized.
