We present a method for growing bit patterned magnetic recording media usingdirected growth of sputtered granular perpendicular magnetic recording media.The grain nucleation is templated using an epitaxial seed layer which containsPt pillars separated by amorphous metal oxide. The scheme enables the creationof both templated data and servo regions suitable for high density hard diskdrive operation. We illustrate the importance of using a process that is bothtopographically and chemically driven to achieve high quality media.
