    • A perpendicular magnetic recording head which moves in a track direction of a recording layer of a perpendicular magnetic recording medium to write information on the recording layer or read information from the recording layer. The perpendicular magnetic recording head includes: the perpendicular magnetic recording medium including a soft magnetic underlayer and the recording layer; a write head including a main pole that applies a magnetic field to, and writes information to, the recording layer and a return pole having a first end which is connected to the main pole and having a second end which is spaced apart from the main pole over an air bearing surface (ABS) of the perpendicular magnetic recording head which is adjacent to the recording layer; and a permanent magnet formed on at least one side of the write head.
    • 垂直磁记录头,其在垂直磁记录介质的记录层的轨道方向上移动以在记录层上写入信息或从记录层读取信息。 垂直磁记录头包括:包括软磁性底层和记录层的垂直磁记录介质; 写头,其包括向记录层施加磁场并向其写入信息的主极;以及返回极,其具有连接到主极的第一端,并且具有与主极间隔开的第二端 在与记录层相邻的垂直磁记录头的空气轴承表面(ABS)上; 以及形成在所述写入头的至少一侧上的永磁体。
