Abstract :
In this study, the magnetic layer was nominally the same, only the thickness of SUL, and EBL were varied. The EBL should be thin to minimize the write gap but thick enough to break the direct exchange coupling between the SUL and the recording layer. We explored the thickness effects of EBL and SUL on recording using multilayer structures.
