A study of write and read spacing loss for perpendicular recording

Abstract

This paper provides the analysis of the write and read spacing loss phenomena for perpendicular recording. Double arctangent transition model including magnetization decay away from a transition revealed the wavelength dependence of the write spacing loss factor. The wavelength dependence of the read spacing loss factor has been found to be influenced by the strength of the head-to-medium magnetic interaction, showing the difference between single pole type and ring heads.
