The influence of the inclination angle of the master pattern on the edge printing characteristics for writing phase servo patterns on perpendicular magnetic recording media was investigated. Even if the master pattern angle is 40 degrees, the printing characteristics are only 10 percent lower than when the angle is 0 degrees. The influence of the inclination angle of the master pattern on the printing characteristics is also small when the bit length is changed. The contribution of the in-plane component of the recording field to magnetization reversal is large in edge printing. Although the perpendicular component of the recording field decreases markedly as the inclination angle of the master pattern increases, edge printing can be used for writing phase servo patterns on slave media.
