7-2 Dependence of recorded magnetization pattern of perpendicular magnetic recording medium on magnetude of recording current

Abstract

A dependence of a recoeded magnetization pattern on a magnetude of a recoeding current was investigated by a computer simuration using the LLG equation. As result, it was shown that the asymmetry of recoeded bit pattern and the distortion of the reproduced waveform changed with the magnitude of recording current.
