Abstract :
In this paper, we present a study comparing the recording performance of perpendicular and longitudinal media. In particular the synchronization requirements of the two cases are compared. A model, which includes media properties, such as easy-axis orientation, switching field distribution (SFD), and head properties, such as head field gradient, is able to reproduce the observed result.
