Effects of Head Skew on Recording Characteristics of Perpendicular Magnetic Recording Medium Using Ring Head

摘要

The recording characteristics of perpendicular media with a ring head were investigated experimentally and by simulation to determine their suitability for high-density perpendicular recording. The recording mechanisms of both perpendicular single-layered and double-layered media were clarified by MFM analysis and simulation of the recorded magnetization pattern with a head skew angle. It was found that the effect of the head skew angle on the recording characteristics differs between single-layered and double-layered media.
