2-Dimensional Observation of Recorded Magnetization Transitions in Perpendicular Recording

Abstract

Two-dimensional magnetic transition shapes written in a perpendicular recording medium were studied by using a large-scale model, which simulates a system of a single pole head and a double layer medium. The magnetization distribution shapes are calculated from the measured stray field distribution on the surface of the recording medium. This paper describes the experimental method and the results derived for a large-scale medium. The results show that sharp magnetic transition is achieved at the track side edge as well as the transition edge in perpendicular recording. © 1989 IEEE
