摘要： Reducing alignment errors between a read element and corresponding write elements permits narrower data tracks and, hence, greater data density on magnetic tape. A method for manufacturing a thin film tape head having multiple write elements and at least one read element corresponding to each write element is provided. Excess material is trimmed from each write element to align the write element with corresponding read elements. The excess material may be track trimmed using a focused ion beam.

摘要翻译： 读取元件与相应的写入元件之间的对准误差降低，使数据轨迹更窄，因此磁带上的数据密度更高。 提供了一种制造具有多个写入元件和至少一个与每个写入元件对应的读取元件的薄膜磁头的方法。 从每个写入元素修剪过多的素材以使写入元件与相应的读取元素对齐。 可以使用聚焦离子束来追踪多余的材料。
