提出了一种高写入灵敏度单极头的新设计。磁头由常规煎饼结构双线圈驱动，夹住主极。两个线圈的外部部分都暴露于空气轴承表面。这些线圈可以产生具有双线连接的尖点场。该新型磁头的高记录灵敏度通过小于0.1 AT/sub 0-P/的小磁动势可以使具有3.5 kOe的高矫顽力的介质饱和这一事实得以阐明。
A new design for a high writing-sensitivity single-pole head is proposed. The head is driven with regular pancake structure dual coils, which sandwiches the main-pole. The outer parts of both coils are exposed to the air bearing surface. These coils can generate a cusp field with bifilar connection. A high recording sensitivity of this new head has been clarified by the fact that a small magnetomotive force of less than 0.1 AT/sub 0-P/ can saturate a medium with a high-coercivity of 3.5 kOe.
