摘要： A perpendicular magnetic write head is provided with a magnetic pole and a pair of side shields disposed on both sides of the magnetic pole in a cross track direction with side gaps in between. Each of the pair of side shields is configured in such a manner that a saturation magnetic flux density thereof increases as a distance from the magnetic pole in the cross track direction increases. Such a configuration allows unwanted divergence component of magnetic flux in a recording magnetic field to be captured while avoiding any excessive capturing of the recording magnetic field, and while preventing any intensity reduction of the recording magnetic field in its entirety. As a result, the recording magnetic field is maintained to have an adequate intensity and spreading of the recording magnetic field is suppressed, so that the recording capabilities are improved.
摘要翻译：垂直磁性写头设置有磁极和一对侧屏蔽件，其设置在磁极的两侧上，并且在横向方向上具有侧间隙。一对侧面屏蔽中的每一个被构造成使得其饱和磁通密度随着在横向上的磁极的距离增加而增加。这样的配置允许在避免记录磁场的任何过度捕获的同时捕获记录磁场中的磁通量的不期望的发散分量，并且同时防止整个记录磁场的强度降低。结果，记录磁场被保持为具有足够的强度，并且抑制了记录磁场的扩展，从而提高了记录能力。
