抄録

Recording mechanism of perpendicular recording was examined using analytical expression of shielded AMR/GMR head response. Pulse shape, roll-off performance, and noise spectra were reasonably explained by the calculated head transfer functions. Comparison with the calculation based on the formulae showed several fundamental characteristics of perpendicular recording: no large media noise at low frequencies in magnetic sense, but simply due to a reflection of a head transfer function: no severe resolution degradation: negligible noise power directly arisen from soft magnetic underlayer. This method will provide a convenient design tool for perpendicular magnetic recording.
