METHOD AND APPARATUS FOR MAGNETIC TRANSFER

摘要

THE PRESENT INVENTION PROVIDES A METHOD FOR MAGNETIC TRANSFER, SAID METHOD COMPRISING THE STEPS OF ARRANGING PERMANENT MAGNETS EACH HAVING MAGNETIC FIELD SYMMETRICAL TO THE AXIS OF THE MAGNETIC POLE AT LEAST ON ONE OF UPPER OR LOWER SURFACES OF THE SLAVE MEDIUM WITH THE AXIS OF THE MAGNETIC POLE DISPOSED IN PARALLEL TO THE SURFACE OF THE SLAVE MEDIUM, ROTATING THE SLAVE MEDIUM OR THE PERMANENT MAGNET IN TRACK DIRECTION, PERFORMING INITIAL DC MAGNETIZATION ON THE SLAVE MEDIUM IN ADVANCE IN TRACK DIRECTION, BRINGING THE MASTER CARRIER FOR MAGNETIC TRANSFER CLOSELY TOGETHER WITH THE SLAVE MEDIUM PROCESSED BY SAID INITIAL DC MAGNETIZATION, AND PERFORMING MAGNETIC TRANSFER BY APPLYING MAGNETIC FIELD FOR TRANSFER IN TRACK DIRECTION REVERSE TO THE DIRECTION OF THE INITIAL DC MAGNETIZATION ON THE SURFACE OF THE SLAVE MEDIUM.
