N2 - In this work, we focus on two important technical issues that need to be overcome before the injection molding technology can be used in the mass production of patterned media, possibly, of small form factor or non-rotating type. Firstly, we describe a fabrication method of a metallic nanostamp through the use of an ultraviolet (UV)-imprinted polymeric nanomaster. Secondly, we examine a method to use a passive heating of the nanostamp to increase the replication quality and to obtain the desired height of the injection-molded nanopillars. Finally, we show that the magnetic film on each injection-molded nanopillars with passive heating has a single magnetic domain.
