Abstract :
This paper presents an analytical solution of the write field distribution for perpendicular recording with effect of the soft underlayer taken into consideration. The solution is based on vector magnetic potential, and the analytical solutions obtained are in good agreement with numerical simulations. It is useful in the design phase of the perpendicular recording heads to investigate the characteristics of the writing field versus structure parameters
