The system further includes a recording medium positioned adjacent the recording head. In one aspect, the recording medium includes a magnetic recording layer wherein the magnetic recording layer has a damping value in the range of about 0.01 to about 0.20. In another aspect, the magnetic pole applies a write field to the recording medium at an angle in the range of about 15 degrees to about 30 degrees from an anisotropic axis of the magnetic recording layer and the field assist source applies a write assist field substantially in a plane perpendicular to the anisotropic axis of the magnetic recording layer. In another aspect, the field assist source has a spatial extent of about 12 nm to about 30 nm. In another aspect, the field assist source applies a circularly polarized write assist field substantially in a plane perpendicular to the anisotropic axis of the magnetic recording layer.

摘要： 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.
