TRACK-WIDTH DEPENDENCE OF TRANSITION JITTER

A simple model that represents the microstructure of magnetic medium a s a rectangular tesselation predicts that the mean-square jitter is in versely proportional to the track width. We test this prediction using different width heads as well as creating different track widths by p artially erasing the original track. We also simulate these experiment s using a micromagnetic model. Our experimental and simulation results are found to be in agreement with the prediction. (C) 1996 American I nstitute of Physics.
