Abstract :
Summary form only given. The width of the media switching field distribution (SFD) is a crucial performance indicator for both longitudinal and perpendicular recording. A broad SFD impacts the SNR and resolution of written transitions. It also indicates the presence of low coercivity grains, which determine the archival lifetime of stored information.
