Abstract
In perpendicular magnetic recording, efforts to enhance magnetic isolation of grains to reduce transition jitter are in progress. However, the grain isolation tends to deteriorate thermal stability. The quality of decayed signal of perpendicular recording media, therefore, becomes more important. In this paper, the influence of thermal agitation on signal quality is investigated for readback waveforms, pulse width, and jitter noise over elapsed time by time-domain analysis.
