    • A magnetic head and method for forming the same. Leads are added to a wafer stack having a free layer, a bias layer, and a spacer layer between the free layer and bias layer. A gap is formed between the leads. A protective layer is added to the wafer stack such that the gap is covered, as well as facing ends of the leads. Material is removed from at least one side area of the wafer stack using the protective layer as a mask. The protective layer is removed. A portion of the bias layer below the gap is processed for reducing a magnetic moment of the bias layer in the portion of the bias layer below the gap for forming a sensor in which magnetic moments of end portions of the free layer are pinned by magnetic moments of end portions of the bias layer, and preferably antiparallel thereto.
    • 一种磁头及其形成方法。 将引线添加到在自由层和偏置层之间具有自由层,偏置层和间隔层的晶片堆叠中。 导线之间形成间隙。 将保护层添加到晶片堆叠中,使得间隙被覆盖,以及面向引线的端部。 使用保护层作为掩模,从晶片堆叠的至少一个侧面区域去除材料。 保护层被去除。 对间隙下方的偏压层的一部分进行处理,以减少偏压层在间隙下方的部分中的偏置层的磁矩,以形成传感器,其中自由层的端部的磁矩由磁矩固定 的偏置层的端部,优选地与其平行。
