Abstract :
Antiferromagnetically coupled (AFC) magnetic media is the current approach to extend the areal density of longitudinal recording media. The authors highlight recent measurements that characterize the write process and thermal stability of AFC media. In particular, they focus on determining the coupling and stability parameters of the individual layers and their contribution to the time scale of the write process.
