发明名称 PERPENDICULAR RECORDING DISCRETE TRACK MEDIUM AND SERVO PATTERN MAGNETIZATION METHOD FOR SAME
摘要 A servo pattern magnetization method is provided, having full-amplitude servo signals, to eliminate the need for intensity modification and waveform shaping during servo signal reading, and to improve the precision of head positioning and enable an increase in track recording density. A servo pattern magnetization method for a perpendicular recording discrete track medium, having a plurality of recording areas and a plurality of servo areas separating the plurality of recording areas, has a process of recording magnetization perpendicular to the substrate and in opposite directions in each of the magnetic recording layers of the plurality of servo blocks, by means of the leakage magnetic field from the soft magnetic layers separated from other servo blocks when a magnetic field is applied.
