Abstract: For magnetic recording technology, much effort is currently devoted to the achievement of areal density up to 1 Tb per square inch and beyond. The enhancement of the magnetic recording areal density is governed by the characteristics of magnetic recording media. Media material with large magnetocrystalline anisotropy (Ku) is required to delay the onset of superparamagnetism. L1(0) and L1(1) phase CoPt thin films have been considered as potential candidates due to their large Ku values and corrosion resistance, which allow smaller thermally stable grains. In this research work, L1(0) and L1(1) CoPt media films were deposited on both MgO single crystal substrates and glass substrates. This research work focused on obtaining desired structure and magnetic properties of L1(0) and L1(1) CoPt media films and investigating the mechanism behind them in order to satisfy the media requirements for high areal density magnetic recording.
