Self-consistent computer calculations for perpendicular magnetic recording

This is the authors' abstract. We don't add key points for this paper.

A comparison of perpendicular and longitudinal recording indicates that conventional heads are suitable for recording on high coercivity media having perpendicular magnetic anisotropy. At equal bit shift and head to disk separation perpendicular recording gives a factor of 2.5 increase in the linear density attained with media in use today.
