The invention is directed to patterned magnetic media for use in magnetic recording
and data storage, and various conditioning techniques that can be used to magnetically
condition the patterns. For example, a medium can be formed to exhibit a pattern
of surface variations defined by patterned areas and non-patterned areas. Techniques
are described for magnetically conditioning the patterned areas. The techniques
may be useful for perpendicular patterned media, i.e., media having patterns formed
on the media surface and having a magnetic anisotropy that is perpendicular to
the plane of the medium. In particular, perpendicular magnetic anisotropy has been
found to be an important factor that allows effective conditioning of patterned
features having relatively small widths.
