Abstract: We investigated via micromagnetic simulation the effect of thermal fluctuation on the stability and transition width of a tilted media with easy axis oriented at 45° and 135° with respect to the vertical along the down-track direction. A dynamic model of the recording process is presented which incorporates a Westmijze head field rotated by 90°. Thermal fluctuations are modeled via a stochastic Landau-Lifshitz-Gilbert equation with a temperature-dependent white-noise field. The dependence of the transition parameter a between adjacent bits and signal-to-noise ratio on temperature is investigated, and comparison between these values of the perpendicular medium and those of the two types of tilted media is performed. © 2005 American Institute of Physics.
