Abstract

The authors discuss work on the magnetic characterization and recording performance of Co/Pd multilayers deposited on various soft underlayer (SUL) and exchange break layer (EBL) structures. The dependence of various recording parametrics were measured as a function of the SUL and EBL thickness and the dimensions of the pole head were investigated. Significant issues behind the transition from dual layer to single layer perpendicular recording are also discussed.
