Abstract
Hard disk drives have been showing a 100% annual growth rate in areal recording density. In order to keep this rate in the future, we must overcome the thermal instability problem of the high-density magnetic recording media. Patterned media is a promising candidate for future high-density magnetic recording because it can improve thermal stability and reduce media transition noise. In this review a new method of fabricating patterned media with an artificially assisted self-assembled mask was described.
