A magnetic recording system is disclosed in which the magnetization
dynamics of the write head and recording medium are highly damped. The
system may comprise a perpendicular recording head having a write pole,
and a recording medium including a hard magnetic recording layer and a
soft magnetic underlayer (SUL). The increased magnetic damping in the
write pole and SUL suppresses precessional motion of the respective
magnetizations, leading to a reduction in transition jitter caused by
spurious head field fluctuations. The damping may be increased by
providing films or multilayer structures that are doped with rare earth
or transition metal elements. Exchange coupled laminates of doped and
undoped layers may optimize both the effective damping and write field in
the recording system.
