Abstract: Isolated pulse shapes and medium noise are analyzed for narrow track recording by micromagnetic simulation. Low density recording is simulated and studied with thin film heads of widths 1.5, 1.0, and 0.5 μm. Isolated pulse shape for a 0.5 μm width recording is severely distorted compared with that for a wide recording. A formula for the PW50 of an isolated pulse is empirically obtained. For a fixed gap length, the first null in the spectrum shifts to lower frequency with a smaller head width. Increases in total noise power are sensitive to narrower heads, especially in the submicron region of the head width. © 1998 IEEE.
