摘要： A compact write element includes a conductive shield layer, an insulating write gap layer, a pole pedestal, a coil, and a conductive pole layer, and, in some embodiments also includes a backgap. The pole pedestal and the coil, and, in some embodiments the backgap, constitute a self-aligned array of components that may be formed in a single masking operation to allow for very tight tolerances between the components for a shorter yoke length. The pole layer is substantially flat and parallel to the conductive shield layer, providing for a shorter stack height. Also, a compact MR read/write head includes such a write element and a magnetic data storage and retrieval system includes the compact MR read/write head having such a write element.

摘要： A magnetic head includes first and second pole tip layers separated by a nonmagnetic gap layer. The pole tips are made of a high magnetic moment material. The right side walls of the first and second pole tips are vertically aligned with each other. Similarly, the left side walls of the first and second pole tips are vertically aligned with one another. The side fringing flux from one pole tip to another is substantially reduced resulting in a magnetic head capable of writing data tracks with well defined boundaries. The possibility of the pole tips operating in magnetic saturation is reduced because the pole tips, formed of high magnetic moment material, is capable of accommodating high coercive force. The magnetic head can be fabricated as an inverted head or a non-inverted head capable of writing on magnetic media with high coercivity and at a high data transfer rate.
摘要翻译：磁头包括由非磁性间隙层隔开的第一和第二极尖层。极尖由高磁矩材料制成。第一和第二极尖的右侧壁彼此垂直对准。类似地，第一和第二极尖的左侧壁彼此垂直对准。从一个极头到另一个极尖的侧边缘通量大大减小，导致能够以良好界定的边界写入数据轨道的磁头。由于由高磁矩材料形成的极尖能够容纳高的矫顽力，所以在磁饱和中操作的极尖的可能性降低。磁头可以被制造为能够以高矫顽力和高数据传输速率在磁介质上写入的倒置头或非倒置头。
