发明名称 Magnetic pattern transferring method for performing a magnetic pattern transfer while correcting a magnetically different part
摘要 A magnetic-pattern transferring method is a method for transferring a magnetic pattern to a magnetic recording medium. The method comprises steps as follows. In a master transferring step, a magnetic field is applied to a master placed close to the magnetic recording medium. The magnetic field excites a magnetic layer having a pattern patterned on the master according to the magnetic pattern. Thereby, the pattern of the magnetic layer is transferred to the magnetic recording medium. In a pattern-difference measuring step, a magnetic condition of the magnetic recording medium is measured so as to measure a magnetically different part between the pattern transferred to the magnetic recording medium and the magnetic pattern. In a magnetic transferring step, a pattern transfer is performed to the magnetic recording medium by using the master while applying the magnetic field so as to correct a magnetic condition of the magnetically different part.
