SNR improvement by variation of recording and media parameters for a HAMR exchange coupled composite media
An exchange coupled composite media structure proposed previously seems to address both the issue of Tc variation in FePt as well as poor SNR/User Density during the HAMR process.Here we examine a thinner 3-6 nm structure that is likely easier to fabricate than the johnny cash style clothing previous 13.5 nm thick structure.We find that increasing
