| Zusammenfassung: | PROBLEM TO BE SOLVED: To record servo information on a lower recording layer having higher magnetic coercivity in a magnetic recording medium having a two layer structure with respect to a magnetic head, magnetic recording device, and magnetic recording method, while suppressing increase in manufacturing cost of the magnetic recording device.SOLUTION: The magnetic head includes a first recording element, second recording element, reproducing element, and head slider on which the first and second recording elements and the reproducing element are provided. The first recording element generates a higher magnetic field than the second recording element in response to an input signal.
【課題】磁気ヘッド、磁気記憶装置及び磁気記録方法において、磁気記憶装置の製造コストの増加を抑えて、２層構造の記録層を有する磁気記録媒体に対し、保磁力の高い方の下層記録層にサーボ情報を記録することを目的とする。【解決手段】磁気ヘッドは、第１の記録素子と、第２の記録素子と、再生素子と、第１及び第２の記録素子及び再生素子が設けられたヘッドスライダを備え、第１の記録素子は、入力信号に対して第２の記録素子より高い磁界を発生する。【選択図】図３ |
