    摘要： A method is disclosed for forming a magnetic shield in which all domain patterns and orientations are stable and which are consistently repeated each time said shield is exposed to an initialization field. The shield is given a shape which ensures that all closure domains can align themselves at a reduced angle relative to the initialization direction while still being roughly antiparallel to one another. Most, though not all, of these shapes are variations on trapezoids.

    摘要： A basic design is disclosed for bottom shield (S1) and top shield (S2) of the reader shields in a magnetic read-write head. The critical part of new design includes an antiferromagnetic film which pins an antiferromagnetically coupled trilayer (AFCT). The simplest embodiment for top shield, for example, would be a film sequence of FM/Ru/FM/AFM. This replaces the normal top shield design which typically comprises a ferromagnetic seed layer and a thicker plated ferromagnetic film. Processes for manufacturing these shields are also described.

    摘要： As track densities increase, it becomes increasingly important, while writing in a given track, not to inadvertently write data in adjoining tracks. This problem has been overcome by limiting the width of material in the ABS plane to what it is at the write gap. The part of the lower pole that is wider than this is recessed back away from the ABS, thereby greatly reducing its magnetic influence on adjacent tracks. Four different embodiments of write heads that incorporate this notion are described together with a description of a general process for their manufacture.

    摘要翻译： 随着轨道密度的增加，在写入给定的轨道时，不会无意中在相邻轨道中写入数据变得越来越重要。 通过将ABS平面中的材料的宽度限制在写入间隙内，已经克服了这个问题。 比这个更宽的下极的部分从ABS背面向后凹陷，从而大大降低其对相邻轨道的磁影响。 描述了包含这一概念的写入头的四个不同实施例以及对其制造的一般过程的描述。
