发明名称 MAGNETIC RECORDING METHOD AND MAGNETIC RECORDING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a high-recording density magnetic recording device wherein a magnetization transition curvature amount of a recording pattern is small. SOLUTION: The center of a heating area is arranged at a track edge side of a recording pattern as compared with the width-direction center position of a main magnetic pole of a recording head, and a recording magnetic field is applied while a medium is locally heated at the time of signal recording. A switching magnetic field of the medium is locally reduced by heating, so that a line 23 where the switching magnetic field of the medium is equal to the recording magnetic field from the head approaches the heating center position as shown in Fig.3 (a), and a desired recording pattern in which the transition curvature amount is reduced can be attained as shown in Fig.3 (b).
