    • A perpendicular magnetic recording head and method of manufacturing the same are provided. The perpendicular magnetic recording head records or reads information on or from a perpendicular magnetic recording medium. The perpendicular magnetic recoding head includes a coil, a main pole, and a return pole. The coil serves as a source for generating a magnetic field. The main pole and the return pole constitute a magnetic path of the magnetic field. The main pole includes an end facing the perpendicular magnetic recording medium. The end includes a leading part serving as a front side and a trailing part serving as a rear side with respect to a movement direction of the perpendicular magnetic recording medium. Both edges of the trailing part are chamfered, and the leading part has a plane inclined with respect to an air-bearing surface (ABS). The return pole has an end spaced from the main pole, and the other end connected with the main pole.
    • 提供了一种垂直磁记录头及其制造方法。 垂直磁记录头在垂直磁记录介质上记录或读取信息。 垂直磁记录头包括线圈,主极和返回极。 线圈用作产生磁场的源。 主极和返回极构成磁场的磁路。 主极包括面向垂直磁记录介质的一端。 该端部包括用作前侧的前导部分和用作相对于垂直磁记录介质的移动方向的后侧的后部。 尾部的两个边缘都被倒角,并且前导部分具有相对于空气轴承表面(ABS)倾斜的平面。 返回极具有与主极间隔开的端部,另一端与主极连接。
