Recorded magnetizations and magnetic fields in media derived by computer simulation

The parameters of magnetic media dependences of the half pulse width, PW₅₀, and output voltage of isolated pulse, E ₀, were investigated using computer simulation. It was found that the squareness in the x direction (Sx) dependences of PW₅₀ and E₀ are different from the saturation magnetization dependences of PW₅₀ and E ₀ and that PW₅₀ hardly changes with Sx for high S* (PW₅₀∝Sx^0.04), although it is proportional to Sx^0.48 for low S *. The corresponding magnetization and the total magnetic field are also investigated for high Sx and low Sx media in three steps. These are the reversed write current, removed head, and reproducing process steps. It is confirmed that transition regions are formed mainly during the reversed write step
