    摘要： A perpendicular magnetic recording write head has a flux conductor in contact with the write pole. The flux conductor is substantially wider than the write pole tip in the cross-track direction and has a blunt end that is recessed from the pole tip end. The region of the flux conductor where its blunt end is in contact with the pole tip is the “choke” point for the write pole, i.e., the point where the flux density is highest. The flux conductor enables the write pole to be made with no flare, or with a flare angle and throat height with a much wider tolerance, which substantially simplifies the manufacturing process. The write head may have a trailing shield and side shields that substantially surround the write pole tip and remove stray fields that may be produced by the flux conductor, so that regions of the recording layer other than the track being written are not adversely affected.

    摘要翻译： 垂直磁记录写头具有与写极接触的磁通导体。 磁通导体在横向磁道方向上基本上比写入磁极尖端更宽，并且具有从磁极末端凹进的钝端。 其钝端与极尖接触的磁通导体的区域是写极的“扼流”点，即磁通密度最高的点。 磁通导体使写磁极能够制成没有耀斑，或具有更宽公差的喇叭角和喉部高度，这大大简化了制造过程。 写头可以具有基本上围绕写磁极尖端的后屏蔽和侧屏蔽，并且去除可能由磁通导体产生的杂散场，使得除了正在写入的磁道之外的记录层的区域不受不利影响。
