摘要： The present application relates to a write gap structure for a magnetic recording head. In illustrated embodiments, the write gap structure includes multiple write gap segments along a beveled pole tip surface between a top edge and a bottom edge of the beveled pole tip surface to provide a narrow write gap proximate to the air bearing surface and a larger write gap behind the air bearing surface. In illustrated embodiments, the narrow write gap segment is formed between the beveled pole tip surface and a lower back surface of front shield and the larger write gap is formed between the beveled pole tip surface and an upper back surface of the front shield.
摘要翻译：本申请涉及用于磁记录头的写间隙结构。在示出的实施例中，写间隙结构包括沿着倾斜磁极尖端表面的顶部边缘和底部边缘之间的斜面磁极尖端表面的多个写入间隙段，以提供靠近空气轴承表面的窄写入间隙和更大的写入间隙在空气轴承表面后面。在图示的实施例中，狭窄的写入间隙段形成在斜面极尖表面和前屏蔽的下后表面之间，并且较大的写入间隙形成在斜面极尖表面与前屏蔽的上后表面之间。

摘要： A write pole may be formed by first depositing a dielectric layer onto a substrate and then patterning the dielectric layer to form a trench with a write pole shape. The trench is subsequently filled with the evaporation deposition of a magnetic material to form a write pole. The trench may have a greater depth dimension than width dimension.
摘要翻译：可以通过首先将介电层沉积到衬底上，然后对介电层进行构图以形成具有写极形状的沟槽来形成写入极。随后填充有磁性材料的蒸发沉积以形成写入极。沟槽可以具有比宽度尺寸更大的深度尺寸。

摘要： A data writer can be configured with at least a write pole separated from a front shield by a non-magnetic gap layer. The front shield may consist of at least a seed layer and a shielding layer with the shielding layer having an easy axis coercivity along a first direction of 4 Oe or more and a hard axis coercivity along a second direction of 0.5 Oe or more.

摘要： A data writer can be fabricated by constructing a write pole to continuously extend from an air bearing surface prior to depositing a first gap layer to continuously extend from the ABS in contact with a first write pole sidewall. A first side shield protrusion can then be formed on the air bearing surface to be separated from the write pole by the first gap layer. A second gap layer may be deposited to continuously extend from the first side shield protrusion along the first write pole sidewall to define a dielectric region on which a second side shield protrusion is formed with the second side shield protrusion separated from the write pole by the first and second gap layers and the first and second side shield protrusions each cantilevered from a common side shield body.
