Medium noise is the dominant noise in ultra-high density disk recording systems. The peak, width and jitter noise are analyzed by micromagnetic simulation. Four different media, with a fixed grain size of 135Å and a coercivity of 2900 Oe, are chosen for medium noise analysis. The linear recording density is increased from 340 KFCI to 750 KFCI, while the area recording density is from 14.3 Gb/in^2 to 31.5 Gb/in^2. The peak-amplitude noise is studied by analyzing the distribution of the peak magnetization M_p in each bit. The distribution of M_p develops from a delta-function around the remanence M_γ at low densities to a flat distribution at extremely high densities. It is found that the transition a-parameter is no longer proportional to the square root of M_γδ, as given in the William-Comstock approximation. The peak jitter noise in the read back voltage is studied by the percentage of the transition jitter in a bit length.
