    • A method provides a PMR transducer. In one aspect, the method includes forming a trench in an intermediate layer using reactive ion etch(es). The trench top is wider than its bottom. In this aspect, the method also includes providing a seed layer using atomic layer deposition and providing a PMR pole on the seed layer. Portion(s) of the seed layer and PMR pole reside in the trench. In another aspect, the method includes providing a mask including a trench having a top wider than its bottom. In this aspect, the method includes providing mask material in the trench, providing an intermediate layer on the mask material and removing the mask material to provide another trench in the intermediate layer. In this aspect, the method also includes providing a PMR pole in the additional trench.
    • 一种方法提供PMR换能器。 一方面,该方法包括使用反应离子蚀刻在中间层中形成沟槽。 沟槽顶部比底部宽。 在这方面,该方法还包括使用原子层沉积提供种子层并在种子层上提供PMR极点。 种子层和PMR极的部分位于沟槽中。 在另一方面,该方法包括提供一种掩模,该掩模包括具有比其底部更宽的顶部的沟槽。 在这方面,该方法包括在沟槽中提供掩模材料,在掩模材料上提供中间层并去除掩模材料以在中间层中提供另一个沟槽。 在这方面,该方法还包括在附加沟槽中提供PMR极点。

    • A method and system for providing a magnetic transducer having an air-bearing surface (ABS) are described. The magnetic transducer includes a base layer, a perpendicular magnetic recording (PMR) pole on the base layer, an additional pole, a write shield, a write gap between the PMR pole and a portion of the write shield, and coil(s) that energize at least the additional pole. The base layer includes a first portion proximate to the ABS and a second portion recessed from the ABS. The first portion is nonmagnetic, while the second portion is magnetic. The PMR pole has a first front portion proximate to the ABS. The additional pole has a second front portion recessed from the ABS. At least a portion of the additional pole resides between the PMR pole and write shield. At least a portion of the write gap resides on the front portion of the PMR pole.
    • 描述了一种用于提供具有空气轴承表面(ABS)的磁换能器的方法和系统。 磁换能器包括基层,基层上的垂直磁记录(PMR)极,附加极,写屏蔽,PMR极与写屏蔽的一部分之间的写间隙,以及线圈, 至少激励附加极点。 基层包括靠近ABS的第一部分和从ABS凹陷的第二部分。 第一部分是非磁性的,而第二部分是磁性的。 PMR杆具有靠近ABS的第一前部。 附加的杆具有从ABS凹入的第二前部。 附加极点的至少一部分位于PMR极和写保护罩之间。 写入间隙的至少一部分位于PMR极的前部。
