Perpendicular recording discrete track medium and servo pattern magnetization method for same

A servo pattern magnetization method, for a perpendicular recording discrete track medium having a recording area having a plurality of recording tracks and a servo area having servo patterns for detecting width-direction positions of each of the tracks,

• each of the plurality of tracks comprising a soft magnetic layer, formed on the substrate, separated from other tracks, and a magnetic recording layer, formed on the soft magnetic layer, separated from other tracks and having an easy axis of magnetization in a direction perpendicular to the substrate surface;
• the servo area having a plurality of servo blocks comprising a servo pattern for detection of the width-direction positions of each track, and each of the plurality of servo blocks comprising a soft magnetic layer, formed on the substrate, separated from other servo blocks, and a magnetic recording layer, formed on the soft magnetic layer, separated from other servo blocks and having an easy axis of magnetization in a direction perpendicular to the substrate surface;
• and
• the magnetization method using a leakage magnetic field from the soft magnetic layers when a magnetic field is applied to record a magnetization, perpendicular to the substrate and in opposite directions, in the magnetic recording layers of each of the plurality of servo blocks.
