Magnetization reversal method, magnetization medium, magnetic recording system and device

摘要

The magnetization reversal method involves applying external magnetic field to a magnetized layer (3) such that magnetization processes around external magnetic field. The external magnetic field is maintained until precision suffices to effect magnetization reversal. Independent claims are also included for the following: (a) magnetization reversal device;; (b) in plane magnetized method; (c) magnetic recording system.
