摘要
An improved soft underlayer structure for perpendicular magnetic recording. The structure includes at least two soft underlayers separated by a non-magnetic spacer layer. The soft underlayer structure incorporates exchange coupling induced anisotropy for improved perpendicular magnetic recording properties, including an improved signal-to-noise ratio (SNR) and reduced adjacent track erasure.
